CompTIA A+ Flashcards: What to Memorize (2026)

Quick Answer

A+ contains more pure memorization than any other CompTIA exam, which makes flashcards genuinely effective — but only for the recall content. Build cards for ports and protocols, cable and connector types, RAID levels, command-line tools and switches, the laser printing process, memory and storage form factors, and the acronym list. Do not build cards for troubleshooting, which requires scenario practice instead.

What Belongs on A+ Flashcards

Ports and protocols. The single highest-yield deck. Port number to service, service to port number, and TCP versus UDP. Build cards in both directions — recognizing a port number is a different skill from producing one.

Cables and connectors. Type, typical use, and where relevant the speed or distance characteristics. Visual cards work well here if your tool supports images.

RAID levels. Configuration, minimum drives, fault tolerance, and the trade-off each makes. A small deck with outsized returns.

Command-line tools and switches. Core 2 tests these heavily. Card the tool to its purpose and the common switches to their effect.

Laser printing process. The stages in order. Order questions are common and the sequence is short enough to be free points.

Memory and storage form factors. Types, where they are used, and how to distinguish them.

Malware removal steps. The documented order. Another sequence that appears reliably.

Safety and environmental procedures. ESD handling, disposal requirements, and documentation types from operational procedures.

The official acronym list. CompTIA publishes it at the end of each objectives PDF. It is effectively a pre-built deck and working through it systematically closes vocabulary gaps you would not otherwise notice.

What Flashcards Cannot Do for You

Troubleshooting is the largest single weakness area on A+, and it is the thing flashcards are worst at. You cannot card "no display output" to a single cause, because the correct answer depends on what else the scenario tells you. Attempting it produces false confidence: you learn one association, then the exam presents the same symptom with different context and keys a different answer.

The same applies to anything phrased in the objectives as "given a scenario." Those bullets are applied knowledge and require practice questions with full scenarios, not stimulus-response pairs.

Conceptual material — cloud service models, virtualization requirements, security control rationale — sits in between. You can card the definitions, but definitions alone will not answer a question asking which model fits a described business need. Card the vocabulary, practise the application.

The practical split that works: flashcards handle the vocabulary and discrete-fact layer, practice questions handle the reasoning layer, and hands-on or simulator time handles the physical and procedural layer. Each covers what the others cannot, and skipping any one of them leaves a predictable gap.

A useful test when deciding whether something belongs on a card: if the answer could change depending on additional context, it is not a flashcard — it is a practice question.

Building Cards That Test Recall, Not Recognition

The most common flashcard mistake is building cards you can answer by recognizing the card rather than knowing the content.

One fact per card. A card listing six ports teaches you the list as a shape. Six separate cards teach you six facts. Split aggressively.

Test in both directions. Port to service and service to port. Command to purpose and purpose to command. Exams ask in whichever direction is inconvenient.

Avoid cues in the question. If the prompt contains a distinctive word that only ever appears with one answer, you are testing pattern matching.

Write the answer before flipping. Out loud or on paper. Passively flipping and thinking "yes, I knew that" is the primary reason people spend weeks on a deck without retaining it.

Keep answers short. A card whose answer is a paragraph is a note, not a card. Notes belong in your study material.

If you use a pre-made deck rather than building your own — which is reasonable given how large the A+ fact set is — verify it against the current objectives first. Decks circulating online are frequently built for retired exam versions and will contain obsolete technology and miss recently added topics.

Running a Schedule That Actually Sticks

Spaced repetition works because it re-tests material just as you are about to forget it. That requires frequency, not duration.

Ten to fifteen minutes daily beats ninety minutes once a week by a wide margin. The daily session is short enough to be sustainable alongside real study, and the frequency is what drives retention.

Sequence the decks with your content study rather than ahead of it. Cards for a domain you have not read yet are just noise. Finish a domain, build or activate that domain's deck, then keep it in daily rotation for the remainder of your preparation.

Run cards at a low-energy time of day and reserve high-energy time for practice questions and troubleshooting scenarios, which demand actual reasoning. Many candidates do cards during a commute or a lunch break and questions in a dedicated evening block.

Retire a card when you have answered it correctly on several spaced occasions without hesitation, but keep the deck available for a final pass in the last week. That last pass is fast, since most cards are retired, and it surfaces the handful that decayed.

The end state you want before exam day is that the recall layer is automatic, so that during the exam your attention goes entirely to the scenario questions that actually require thought.

Expert Insight

The reason flashcards work unusually well for A+ is not that memorization wins exams — it is that automating the recall layer frees working memory during the exam itself. Candidates who have to stop and reconstruct a port number burn attention they need for the troubleshooting scenario the question is actually built around. The deck is not the point; the cognitive headroom it buys is.

Study Tips

• Build cards in both directions — recognizing a port number and producing one are different skills.

• Say or write the answer before flipping. Passive flipping is why decks stop working.

• Verify any pre-made deck against the current objectives; many circulating decks target retired exam versions.

• Run cards at low-energy times and save high-energy time for troubleshooting scenarios.

• The acronym list in the objectives PDF is a ready-made deck and closes vocabulary gaps you would not otherwise find.

Common Mistakes

• Making flashcards for troubleshooting, where the correct answer depends on scenario context.

• Packing several facts onto one card, which teaches the card rather than the content.

• Doing long infrequent sessions instead of short daily ones, which defeats spaced repetition entirely.

• Using an outdated pre-made deck and memorizing technology that is no longer tested.

• Treating a completed deck as readiness. Flashcards cover recall only — the scenario half of the exam is untouched by them.
