• Subnetting Confusion: Practicing subnetting problems repeatedly and using tools or cheat sheets can help develop speed and accuracy. 
• Command Line Intimidation: Spend time in Packet Tracer or GNS3 using CLI until the commands become second nature. 
• Information Overload: Break study sessions into smaller, focused goals. Don’t try to memorize everything at once. Use visual aids and concept maps. 
• Exam Anxiety: Simulate the testing environment through mock exams. Understand the format so that nothing feels unfamiliar on exam day. 

Every candidate faces hurdles, but with a structured approach and persistence, most find the CCNA to be an achievable and rewarding goal.
