CompTIA A+ Study Guide: How AI Can Help You Get Certified in 2026

The CompTIA A+ certification is the industry-standard entry-level IT certification, validating foundational IT skills across hardware, software, networking, and troubleshooting. It consists of two exams: Core 1 (220-1101) covering mobile devices, networking, hardware, virtualization/cloud computing, and hardware/network troubleshooting; and Core 2 (220-1102) covering operating systems, security, software troubleshooting, and operational procedures.

Each exam has a maximum of 90 questions (a mix of multiple-choice, drag-and-drop, and performance-based questions) and lasts 90 minutes. The passing score is 675 out of 900 for Core 1 and 700 out of 900 for Core 2. CompTIA A+ is the most widely held IT certification globally and is a prerequisite for many IT support, help desk, and desktop support positions. Many employers and government agencies (including DoD) require or prefer A+ certified candidates.

Most candidates study for CompTIA A+ over 1-3 months, depending on their existing IT experience. A timeline for beginners:

• Weeks 1-3: Core 1 study — work through video courses (Professor Messer, Mike Meyers) covering hardware components, networking basics, mobile devices, and cloud concepts; build flashcards for port numbers, cable types, and connector specifications
• Weeks 4-5: Core 1 practice and exam — complete practice tests, review performance-based question (PBQ) formats, and take the Core 1 exam
• Weeks 6-8: Core 2 study — cover operating systems (Windows, macOS, Linux), security concepts, malware types, and troubleshooting methodologies; build flashcards for command-line tools and security protocols
• Weeks 9-10: Core 2 practice and exam — complete practice tests focusing on troubleshooting scenarios and operational procedures, then take Core 2

Many candidates take Core 1 first, then study for Core 2 while the testing experience is fresh. Hands-on practice — setting up virtual machines, configuring network settings, using command-line tools — is essential alongside book study.

CompTIA A+ is a memorization-heavy certification with hundreds of specific technical details that must be recalled accurately:

• Port number flashcards: The exam tests dozens of TCP/UDP port numbers (HTTP 80, HTTPS 443, DNS 53, SMTP 25, etc.). AI generates flashcards from your prep course recordings, pairing each port number with the protocol and use case your instructor described.
• Hardware specification cards: Connector types, cable categories (Cat5e, Cat6, Cat6a), Wi-Fi standards (802.11a/b/g/n/ac/ax), and RAM types — AI flashcards capture these specifications with the visual descriptions and mnemonics your instructor uses.
• Troubleshooting methodology notes: Performance-based questions test your troubleshooting approach. Recording your instructor's walkthrough of troubleshooting scenarios creates a reference library of systematic approaches you can review before the exam.
• Command-line reference: Core 2 tests command-line tools for Windows, macOS, and Linux. AI generates quick-reference cards from your prep course's command demonstrations.

Notella is ideal for CompTIA A+ preparation because the certification is heavily detail-oriented. Record your Professor Messer or Mike Meyers video study sessions and Notella generates flashcards for every port number, cable type, protocol, and troubleshooting step discussed. Instead of pausing videos to write flashcards by hand, you capture everything automatically.

The flashcard feature handles the volume of CompTIA A+ memorization material — hundreds of specific facts across networking, hardware, operating systems, and security. AI organizes these by exam objective, so you can review by topic area (e.g., all networking-related cards, all security-related cards).

For troubleshooting practice, record yourself working through practice scenarios and explaining your reasoning. Notella creates notes from these sessions, building a personal troubleshooting reference guide that mirrors the systematic approach the exam rewards.

Strategies from candidates who passed both A+ exams on the first attempt:

1. Use Professor Messer's free videos as your foundation — they're comprehensive, well-organized, and align directly with the exam objectives; supplement with paid courses if needed
2. Practice with virtual machines — install Windows, macOS, and Linux VMs to get hands-on experience with the operating system tasks the exam tests; reading about command-line tools is no substitute for using them
3. Memorize port numbers and protocols early — these appear throughout both exams; make flashcards and review them daily starting from week one
4. Focus on performance-based questions (PBQs) — these are the hardest questions and appear first on the exam; practice with simulation tools and lab environments
5. Take the exam when you're scoring 85%+ on practice tests — CompTIA exams have a clear passing threshold; consistent 85%+ on reputable practice exams (Jason Dion, CompTIA CertMaster) means you're ready
