Understanding the Structural and Scoring Differences Between the ACT and SAT
When it comes to applying to college in the United States, the ACT and SAT are two standardized tests that play a central role in admissions decisions and scholarship qualifications. Though many colleges accept scores from either test without preference, they are not identical in structure, content, or testing strategy. Understanding how these two exams differ can help students decide which is the better fit for their learning style and academic strengths.
The ACT and SAT both evaluate skills in reading, writing, and math. However, the ACT includes a science reasoning section, and until recently, both offered optional essay components. With recent changes to the SAT—including the removal of its essay and subject tests—it’s now even more critical to understand how each test functions. Whether you’re a fast test-taker who excels under time pressure or a careful thinker who prefers a bit more time to work through problems, choosing the right test can significantly affect your final score and college options.
Both the ACT and SAT are multiple-choice, standardized tests that students usually take in their junior or senior year of high school. Despite their similar purposes, they differ in their section breakdown, number of questions, time allocations, and scoring methods.
The ACT is composed of four main sections: English, Math, Reading, and Science. It also offers an optional Writing (essay) section. The SAT, on the other hand, consists of two main sections: Evidence-Based Reading and Writing (which includes a Reading Test and a Writing & Language Test), and Math (split into calculator and no-calculator sections). The SAT once included an optional Essay section, but that has been discontinued for most test-takers since 2021.
Each section of these tests assesses a distinct set of academic skills, and the way those skills are tested varies between the two exams. Time management is a major concern on both tests, but the ACT generally allows less time per question, making it more fast-paced.
The ACT English section and the SAT Writing and Language section both evaluate grammar, punctuation, sentence structure, and rhetorical skills. They ask students to revise and edit passages to improve clarity, correctness, and style.
The ACT English section consists of 75 questions to be answered in 45 minutes. This means test-takers must work at a brisk pace of 36 seconds per question. The section features five passages, each followed by multiple questions. The questions typically involve identifying grammatical errors, improving sentence clarity, and understanding writing style and organization. Because of the rapid pace, students must be able to quickly recognize common errors and confidently choose the best correction.
In contrast, the SAT Writing and Language section contains 44 questions spread across four passages and must be completed in 35 minutes. This allows for a slightly more generous 48 seconds per question. The passages in the SAT may include graphics like charts or tables, and students may be asked to correct sentences in a way that aligns with the data presented. Additionally, the SAT may test more complex sentence structures and ask students to make more nuanced editorial decisions.
While the fundamental skills being tested are the same—grammar, syntax, and style—the ACT tends to focus on volume and speed, while the SAT favors careful analysis and editing. Students who excel at quickly identifying and correcting grammatical mistakes may perform better on the ACT, while those who prefer to deliberate over fewer, more detailed questions may find the SAT more suitable.
Reading comprehension is a critical part of both the ACT and SAT, and both tests present passages that must be read and analyzed for content, structure, tone, and meaning. However, differences in question style, passage length, and time pressure can influence which test better suits a student.
The ACT Reading section includes 40 questions and must be completed in 35 minutes, giving about 53 seconds per question. There are four passages, each accompanied by ten questions. One passage is typically split into two shorter texts for comparative analysis. The reading passages are drawn from fiction, social science, humanities, and natural sciences, and questions tend to focus on straightforward comprehension, cause-and-effect relationships, author purpose, and vocabulary in context.
The SAT Reading section consists of 52 questions to be answered in 65 minutes, which allows for roughly 75 seconds per question. This section includes five passages, including one passage drawn from U.S. or world literature, one historical or foundational document, one social science piece, and two science-related passages. SAT reading questions often require deeper analytical thinking, especially when interpreting the author’s tone, understanding historical context, or analyzing evidence presented in the text.
Additionally, SAT passages can include older or more complex writing, particularly in historical documents or classical literature excerpts. These passages may feature formal language or dense sentence structure that can be challenging for some test-takers.
In summary, the ACT Reading section rewards quick processing and solid comprehension skills, while the SAT’s longer reading section offers more time but expects a higher level of text analysis. If you are a fast reader who works well under pressure, the ACT might be a better choice. If you prefer more time to think and are comfortable with complex texts, the SAT may suit you better.
Math is an area where the differences between the ACT and SAT become more apparent, not just in structure and timing but also in the types of questions and calculator policies.
The ACT Math section includes 60 questions to be answered in 60 minutes, with one minute allotted per question. It allows calculator use for all questions and consists entirely of multiple-choice items. The content ranges from pre-algebra and algebra to geometry, trigonometry, and a small number of pre-calculus concepts. Students are expected to move quickly through the section and apply math formulas efficiently. There is also a tendency for the ACT to focus more on geometry and trigonometry than the SAT.
The SAT Math section is divided into two parts: one that allows calculator use and one that does not. The non-calculator portion consists of 20 questions (25 minutes), while the calculator-allowed section has 38 questions (55 minutes), making a total of 58 questions in 80 minutes. This allows more time per question—about 83 seconds. The SAT math questions include both multiple-choice and grid-in formats, where students must supply their answers. Content-wise, the SAT emphasizes algebra, problem-solving, data analysis, and some advanced math topics. There is less emphasis on geometry and trigonometry compared to the ACT.
Calculator policy is another important distinction. Because the ACT permits calculators throughout, students who rely on calculators may find it more comfortable. On the SAT, being proficient in mental math and manual calculation is key, especially in the no-calculator section.
Another subtle difference is in question style. SAT math questions often require multi-step reasoning and can be more word-heavy, involving context-based problem solving. ACT questions tend to be more direct and computational.
Students who are confident in their quick math skills and prefer consistent calculator use may lean toward the ACT, while those who are stronger in algebra and reasoning-based math and prefer a slower pace may do better on the SAT.
The science section is one of the most distinctive features of the ACT, as the SAT does not include a separate science component. The ACT Science section is 35 minutes long and contains 40 questions based on seven passages. Each passage presents scientific data in the form of graphs, tables, or research summaries. Students are asked to interpret data, identify trends, analyze experiments, and draw conclusions.
Importantly, the ACT Science section does not test in-depth science knowledge. Instead, it evaluates scientific reasoning and critical thinking. Familiarity with the scientific method, understanding experimental design, and the ability to read scientific charts are more important than memorizing biology or physics facts.
Because the SAT lacks a standalone science section, it integrates science-related content into its Reading and Writing sections. For example, a reading passage might present a study or an article on a scientific topic, and students are expected to analyze the data and draw conclusions.
Students who are comfortable with interpreting graphs, tables, and experimental summaries may find the ACT Science section a strong point. Those who are less inclined toward scientific reasoning or who prefer not to have an additional content area to prepare for might feel more comfortable with the SAT.
Until recently, both tests included optional essay sections, but now only the ACT retains this component. The ACT Writing test is a 40-minute essay based on a single prompt about a social issue. Students are presented with three perspectives on the issue and are asked to analyze them, develop their viewpoint, and support it with logical reasoning and examples.
The essay is scored separately and does not impact the composite ACT score. Some colleges may require or recommend the ACT Writing score, so it’s important to research individual school requirements before deciding whether to skip it.
The SAT once included an optional essay, but it was phased out in 2021 for all but a few special exceptions (such as school-day administrations in certain states). As a result, most students do not need to prepare for an SAT essay at all.
Students who are confident writers and want to showcase their analytical and argumentative skills may benefit from completing the ACT Writing section, particularly if applying to a school that values that component.
This first part has outlined the structural and content-related differences between the ACT and SAT. From the ACT’s inclusion of a science section and optional essay to the SAT’s emphasis on deep reading and algebra-focused math, the choice between the two depends largely on how students prefer to work through academic material. Some students thrive under the fast-paced, direct questioning style of the ACT, while others do better with the SAT’s slower pace and multi-step reasoning problems.
Timing is one of the most critical differences between the ACT and the SAT. It affects not just how long the overall test takes but also how much time is available for each question. Students who struggle with time pressure may find one test more comfortable than the other.
The ACT is known for its strict time limits and fast pacing. Each section is dense with questions and requires quick decision-making and efficient test-taking strategies. Here is a breakdown of the ACT’s timing per section:
The total testing time for the ACT without the essay is approximately 2 hours and 55 minutes. If you take the optional essay, the full test takes around 3 hours and 40 minutes.
The SAT, by contrast, offers a bit more time per question, particularly in the Math and Reading sections. Here’s the SAT breakdown:
The SAT’s total testing time is around 3 hours. The essay section has been discontinued, so students do not need to budget additional time for writing unless taking a school-specific test that still includes it.
The key takeaway is that the SAT tends to favor students who prefer more time to consider each question, while the ACT may appeal to those who are comfortable working at a faster pace. Practice exams can help identify which timing structure works better for each student.
The ACT and SAT use completely different scoring scales, which can make comparisons between the two challenging. However, colleges are familiar with both systems and often use concordance tables to compare scores from each exam.
ACT Scoring:
For example, a student who scores 30 on English, 28 on Math, 31 on Reading, and 29 on Science would have a composite ACT score of 29.5, which is rounded to 30.
SAT Scoring:
For example, a student who scores 680 in ERW and 720 in Math would have a total SAT score of 1400.
Average Scores:
Because the scoring systems are so different, direct comparisons can be misleading without concordance tools. The College Board and ACT have worked together to provide official concordance charts that allow students and colleges to compare scores fairly across the two exams.
A key feature shared by both tests is that guessing is not penalized. This means that students should never leave a question blank, as there is no deduction for incorrect answers—only points awarded for correct ones.
This hasn’t always been the case. Before 2016, the SAT deducted a fraction of a point for each wrong answer, discouraging random guessing. However, this policy has been eliminated. Now, both the ACT and SAT use “rights-only” scoring, where you gain points for correct answers and receive no penalty for incorrect ones.
Strategic guessing can improve a student’s overall performance. For example:
This policy encourages students to attempt every question, even if they are unsure of the answer. Developing a test-taking strategy that includes intelligent guessing can help maximize scores on both exams.
Most colleges in the United States accept both ACT and SAT scores equally. There is no inherent preference for one over the other, especially among competitive institutions. Schools use standardized test scores in several ways during the admissions process:
For example, if a student takes the SAT twice and scores 650 in Reading and Writing the first time and 720 the second time, the higher score of 720 may be used regardless of the test date. The same applies to Math.
Not all colleges superscore, so it’s important to check individual school policies. If a school does, it may be beneficial to retake the test and focus on improving weaker sections.
Test-optional does not mean test-blind. Most test-optional schools will still consider submitted scores. Some schools remain test-required, especially for out-of-state students, athletic recruits, or specific scholarship programs.
The cost of taking the ACT or SAT is another factor to consider. While both exams are similarly priced, small differences can affect a student’s decision, particularly if they plan to take the test multiple times or submit scores to many schools.
ACT Costs:
SAT Costs:
Students who cannot afford these fees may qualify for fee waivers from the ACT or College Board, which allow for free registration, free score reports, and even fee waivers for college applications. It’s worth exploring these options with a school counselor.
Both tests allow students to send scores to colleges for free, but the window for choosing those schools is limited. For the ACT, students must select schools by the Thursday after the test. For the SAT, the window extends to nine days after test day.
Once the free reporting period ends, additional reports cost money. Planning and knowing where you want to send your scores can save you money and time. Also, if a student plans to apply to many schools, it might be worth taking the test early enough to retest if needed and optimize the superscore or final submission.
Understanding each college’s specific test policies—including whether they superscore, require the ACT essay, or are test-optional—is a critical step in planning test strategy. Students can make a list of schools and create a table comparing score requirements, deadlines, and policies to stay organized.
This guide has focused on the logistical and evaluative differences between the ACT and SAT. From timing and scoring mechanics to how colleges interpret and use test results, these factors all contribute to the decision about which test to take. Neither test is inherently easier or harder; instead, the better option depends on individual strengths, preferences, and the policies of target colleges.
Once students understand the structural and scoring differences between the ACT and SAT, the next step is effective preparation. Whether a student plans to take one of the exams or both, success depends on creating a targeted study plan that suits their learning style and academic needs. The ACT and SAT require mastery of core high school subjects, but each test emphasizes different skills and formats. Knowing how to prepare for these differences can have a major impact on performance.
In this part, we’ll explore the best preparation strategies for each test, tools to help improve your score, and how to use practice tests to determine which exam aligns better with your strengths. We’ll also discuss specific areas of focus for each section—English, Math, Reading, Science (for the ACT), and the Essay (for those choosing the ACT Writing section).
Before choosing which test to commit to, students should start with a diagnostic approach. Taking a full-length, timed practice ACT and SAT is one of the most reliable ways to determine which test feels more comfortable. Practice exams simulate the real testing experience and can help identify strengths and weaknesses in content knowledge, pacing, and question types.
After taking both practice tests, students should analyze the following:
By reviewing these areas, students can make a more informed decision about which test to prepare for. In some cases, the difference in performance may be small enough that personal preference or test date availability becomes the deciding factor. In others, one test may show a significant score advantage, making the choice clear.
While the ACT and SAT have unique structures, their shared goal—assessing academic readiness—means many preparation techniques apply to both exams. The following strategies can improve performance regardless of which test you choose:
ACT English:
ACT Math:
ACT Reading:
ACT Science:
ACT Essay (Optional):
SAT Reading:

Once you’ve practiced both exams, compare your performance:
Here are general tendencies that may help you decide:
It’s important to recognize that one test is not universally easier or better. The key is which test fits your academic strengths, thinking style, and pace.
Students today have a wide array of study tools available:
Regardless of the resource you choose, the key is consistency and feedback. Practice regularly and adjust your approach based on performance.
Effective preparation for the ACT or SAT is about more than just studying content. It involves understanding the structure of the test, managing your time, and using the right strategies to answer questions accurately and efficiently. Practice exams are essential in deciding which test suits you better and in building familiarity with the pacing and style of the test.
Choosing between the ACT and SAT is not always just about format, timing, or scoring preferences. A variety of external and situational factors can also influence your decision. These include the accessibility of test centers, available test dates, eligibility for accommodations, whether you’re an international student, and even the recent shift toward test-optional college admissions policies.
As college admissions become increasingly holistic, the importance of a single test score may be decreasing, but it has not disappeared. High scores can still give applicants a competitive edge, especially for scholarships and competitive programs. In this final part, we will explore how these broader factors fit into your test-planning strategy and what role standardized testing plays in the bigger picture of applying to college.
Test availability may seem like a minor consideration, but it can significantly affect your ability to prepare for and take your chosen exam, especially if you have a tight college application timeline or limited access to testing centers.
ACT Test Dates and Registration:
SAT Test Dates and Registration:
For students with tight deadlines or those who want to take both exams, it’s essential to map out testing dates early in your high school career. Test planning is especially important if you’re also managing AP exams, IB coursework, or major extracurricular commitments.
Both the SAT and ACT offer testing accommodations for students with documented disabilities. These may include extended time, extra breaks, use of assistive technology, or accommodations for reading or writing challenges.
ACT Accommodations:
SAT Accommodations:
While both organizations offer similar supports, some students find the ACT accommodations process slightly more flexible, while others appreciate the centralized system of the College Board. Students with learning differences should evaluate which test format and accommodations better suit their needs. For example:
For international students planning to apply to colleges in the United States, the choice between the ACT and SAT can be influenced by test availability, familiarity with the exam, and academic background.
Test Center Locations:
Language Considerations:
Math Focus:
College Preferences:
International students should also be mindful of time zones, test center travel logistics, and visa or passport requirements. Register early, as international seats often fill quickly.
In recent years, a growing number of colleges and universities have adopted test-optional policies, meaning students are not required to submit ACT or SAT scores as part of their application. While this shift gained momentum due to the COVID-19 pandemic, many schools have chosen to continue test-optional practices indefinitely.
However, test-optional does not mean test-blind:
For students applying to competitive or selective colleges, submitting a high standardized test score can strengthen their application, even when it is not required. Test-optional policies are designed to level the playing field, but they don’t necessarily reduce the value of a strong test result.
Some colleges are also test-flexible, meaning they accept other types of standardized assessments in place of the SAT or ACT, such as AP test scores, IB scores, or the CLT (Classic Learning Test). It’s important to read the admissions policy of each school carefully.
While most students focus on the role of ACT or SAT scores in gaining college admission, these scores can also have long-term impacts that extend beyond getting into a specific university.
Scholarships and Financial Aid:
College Course Placement:
Resume Boost for Internships:
Graduate School Applications:
Career Placement and Employer Considerations:
Ultimately, students should view the ACT or SAT not just as an admissions hurdle, but as a possible opportunity to improve their future academic and financial outcomes.
Here is a quick summary of additional considerations to keep in mind:
Factor | ACT | SAT |
Test Dates | 7 U.S. dates, fewer international offerings | 7 U.S. dates, broader international availability |
Time Per Question | Faster-paced overall | Slower pacing per question |
Calculator Policy | Calculator allowed for all math questions | One math section, no calculator allowed |
Reading Style | More straightforward passages | Includes older, more complex texts |
Science Section | Yes – dedicated science reasoning section | No – integrated into reading/writing sections |
Accommodations Process | School-coordinated, ACT review | Centralized SSD process (College Board) |
International Accessibility | Less consistent abroad | More test centers globally |
Test-Optional Compatibility | A strong score is still useful for scholarships/admissions | Same – optional but still beneficial |
The decision to take the ACT or SAT isn’t just about content preference—it’s also influenced by your location, accommodation needs, scholarship eligibility, and long-term academic goals. As more schools become test-optional, students have more flexibility, but standardized test scores can still serve as valuable academic credentials.
Whether you choose the ACT, the SAT, or both, early planning and strategic preparation are the keys to success. By understanding how each test aligns with your strengths and personal situation, you can confidently move forward in your college journey, armed with the tools to make the most of your abilities and opportunities.
Selecting between the ACT and SAT is a significant decision in the college admissions process, but it doesn’t have to be overwhelming. Both tests serve the same purpose: they help colleges evaluate your academic readiness for higher education. However, because they assess your skills differently—through varying formats, pacing, question styles, and subject emphases—choosing the right one can be the difference between a good score and a great one.
The most important takeaway is that there is no universally better test. The right choice depends on your strengths, learning style, test-taking habits, academic goals, and personal circumstances.
If you’re a student who:
If you’re a student who:
Beyond the format, you also have to consider test availability, accommodations, international access, and your college list. In an era where more institutions are test-optional, standardized test scores still carry weight for scholarships, honors programs, and placement, even if they’re not required for admission.
Most importantly, remember that these exams do not define your potential. They are just one part of a broader application that includes your grades, activities, recommendations, and personal story. Still, a strong test score can enhance your application and open doors to financial aid and selective opportunities.
Once you’ve chosen your path, commit to thoughtful, consistent preparation. Use official practice materials, take full-length timed tests, and focus on improving your weakest areas. The more familiar you become with the test, the more confident and successful you’ll be on test day.
Finally, keep things in perspective: your college journey is a marathon, not a sprint. Whether you take the ACT, SAT, or both, what matters most is how you use the results to your advantage—and how you grow from the process along the way.
