•Take notes and create flashcards for key concepts

Weeks 5-8: Core 1 Practice

•Complete practice questions daily (minimum 50 questions/day)
•Focus on weak areas identified through practice tests
•Practice with performance-based questions (PBQs)

Week 9: Core 1 Exam

•Review weak areas and take final practice exam
•Schedule and take Core 1 exam when scoring 85%+ on practice tests

Weeks 10-16: Core 2

High-Priority Topics to Master

Core 1 (220-1101)

1.
Hardware Components: RAM types, CPU sockets, storage interfaces (SATA, NVMe), power supplies, motherboard form factors
2.

3.
Mobile Devices: Laptop hardware replacement, mobile device synchronization, wireless connectivity troubleshooting
4.
Troubleshooting: Methodical approach to hardware and network issues

Core 2 (220-1102)

1.
Operating Systems: Windows installation, command-line tools (ipconfig, sfc, chkdsk), Control Panel vs Settings, macOS/Linux basics
2.
Security: Malware types, best practices (encryption, MFA), physical security, wireless security protocols
3.
Software Troubleshooting: Boot issues, application crashes, blue screens
4.
Operational Procedures: Ticketing systems, change management, backup strategies, safety procedures

Exam Day Strategies

Skip PBQs initially: Performance-based questions appear first but take the most time. Flag them and return after completing multiple-choice questions.
Read questions carefully: Look for keywords like "BEST," "FIRST," "MOST," and "LEAST." CompTIA often has multiple correct answers but wants the BEST one.
Eliminate obviously wrong answers: Narrow down to 2 options before making your final choice.
Manage your time: You have 90 minutes for up to 90 questions. Aim for 1 minute per multiple-choice question, leaving 20-30 minutes for PBQs.
Don't panic: If you encounter a topic you don't recognize, use logic and eliminate answers. CompTIA tests critical thinking, not just memorization.

Final Tips for Success

✓ Practice Consistently

Daily practice is better than cramming. Even 30 minutes a day will yield better results than weekend marathons.

✓ Get Hands-On

Lab experience is crucial. Set up virtual machines, practice with real hardware, and experiment with Windows/Linux commands.

✓ Join Study Groups

Communities on Reddit (r/CompTIA) and Discord can provide support, answer questions, and keep you motivated.

✓ Don't Schedule Too Early

Only book your exam when you're consistently scoring 85%+ on practice tests. Confidence matters on exam day.
