If you’re preparing for the CompTIA A+ exam — specifically Core 1 (220-1201) and Core 2 (220-1202) — practice questions are one of the most powerful tools in your study arsenal. But here’s the thing: most people use them wrong. They treat practice tests like a final exam, rushing through questions and celebrating a passing score without understanding why each answer is correct. If you want to walk into the testing center with real confidence, you need a smarter approach to CompTIA A+ practice test tips that builds genuine understanding, not just familiarity with answer choices. Let’s break down exactly how to make every practice question count.
Why Practice Questions Are More Than a Score Checker
The CompTIA A+ exams are no joke. You have 90 minutes to answer up to 90 questions — including multiple-choice, drag-and-drop, and performance-based questions (PBQs) — and you need to score 675/900 on Core 1 and 700/900 on Core 2 to pass. That’s a meaningful bar, and it requires more than surface-level memorization.
Practice questions serve three distinct purposes when used correctly:
- Diagnosis: They reveal which domains you haven’t truly mastered yet.
- Reinforcement: Repeated exposure to exam-style phrasing trains your brain to recognize concepts under pressure.
- Simulation: They prepare you for the cognitive load of 90 questions in 90 minutes.
The mistake most candidates make is skipping straight to purpose three without doing purposes one and two first. Don’t do that.
Tip 1: Study the Explanation, Not Just the Answer
After every practice question — especially the ones you get wrong — read the full explanation before moving on. This is non-negotiable. The CompTIA A+ exam doesn’t test isolated facts; it tests your ability to apply concepts in context. When you understand why SSH uses port 22 and Telnet uses port 23 (and why one is preferred over the other from a security standpoint), you can answer any question phrased around those ports, not just the exact one you practiced.
For every wrong answer, ask yourself:
- What did I misunderstand about the concept?
- Which domain does this fall under?
- How would this concept appear in a real-world IT scenario?
This habit transforms a wrong answer from a discouraging failure into a targeted study opportunity.
Tip 2: Map Weak Areas to Exam Domains
The CompTIA A+ Core 1 exam has five domains, with Hardware & Network Troubleshooting carrying the heaviest weight at 29%. Core 2 leads with Operational Procedures at 30%, followed by Security at 26%. If your practice results consistently show weak performance in these high-weight domains, that’s exactly where your study time should go.
Don’t just track your overall score. Track your performance by domain. A 70% overall score could mask a critical gap — maybe you’re acing Networking but struggling badly with Virtualization & Cloud Computing. An adaptive study tool that pinpoints these gaps for you is infinitely more efficient than retaking the same practice test repeatedly.
Tip 3: Simulate Real Exam Conditions
When you’re ready to do a timed practice run, treat it like the real thing. That means:
- No phone distractions
- No pausing to look things up mid-question
- Strict time limits — 90 minutes, 90 questions
- Flagging questions you’re unsure about and returning to them (just like the real exam interface)
This builds the mental stamina and pacing instincts you’ll need on exam day. Many candidates run out of time not because they don’t know the material, but because they weren’t prepared for the sustained focus the exam demands.
Tip 4: Use Spaced Repetition, Not Marathon Sessions
Research consistently shows that spaced repetition — reviewing material at increasing intervals — produces stronger long-term retention than cramming. Instead of doing 90 practice questions in one sitting every weekend, try 15-20 questions daily, focusing on topics you’ve recently studied. Revisit concepts you got wrong two or three sessions later to confirm they’ve actually stuck.
This approach works especially well for the memorization-heavy parts of the A+ exam — port numbers, RAID levels, cable types, and acronyms like DHCP, DNS, BIOS/UEFI — where repetition over time beats repetition in volume.
Tip 5: Don’t Skip Performance-Based Questions
PBQs are the drag-and-drop and simulation-style questions that appear on both Core 1 and Core 2. They’re often the most intimidating, and many candidates skip PBQ practice entirely. That’s a mistake. These questions test your ability to do something — configure a network, match cables to ports, sequence a troubleshooting process — not just recall a fact. Look for practice resources that include scenario-based and drag-and-drop style questions, and take them seriously.
