CompTIA A+ Certification Guide for Beginners

What CompTIA A+ covers, how the 220-1201 and 220-1202 exams work, and a step-by-step plan to earn the certification as a complete beginner.
Continue readingTurn the free CompTIA exam objectives PDF into a checklist, study map and readiness tracker — a practical method that works for A+, Network+ and Security+.

Every CompTIA exam ships with a free document that tells you, line by line, what the test can ask — and most candidates skim it once and never open it again. That document is the exam objectives PDF, downloadable at no cost from comptia.org for every live exam, and using it properly is the single cheapest upgrade you can make to your preparation. The exam is written against the objectives; your study plan should be too.
This guide shows you how to read the document's structure and convert it into a working checklist and study map. It applies equally to A+, Network+, Security+ and the rest of the CompTIA line-up — how to build a full week-by-week study plan, and how to choose resources, are covered in the per-exam preparation guides linked throughout.
Open any CompTIA objectives PDF and you will find the same anatomy:
The verb that opens each objective tells you the depth the exam expects, and this is the most commonly missed signal in the whole document:
Sorting every objective into those three buckets before you start studying tells you, in about twenty minutes, how much of your preparation must be hands-on rather than book-based.
The second job of the objectives, after planning, is scoping. Study resources drift: books include legacy material, video courses pad, forum wisdom ages badly. Whenever a resource covers something, ask which objective row it maps to. No row, no study time — and conversely, any row your chosen resource never touches needs a second resource to fill it. When an exam version changes (CompTIA revises each exam every few years and retires the old code), rebuilding the spreadsheet from the new PDF shows you precisely what changed, rather than guessing from a book's edition number.
The same mapping works in reverse for practice questions: when you miss a question, trace it back to its objective row and mark that row down. Over a few sessions this turns a raw score into a per-domain diagnosis. A timed CompTIA practice test becomes far more useful when every wrong answer lands on a specific row of your checklist instead of vanishing into a percentage — ExamPractice's free samples and subscriber simulation mode are built around exactly this objective-by-objective review loop.
Take a Security Operations-style objective phrased "Given a scenario, analyse indicators of malicious activity", with bullets listing attack types. Applied to the method:
If your paragraph of notes on an objective would read the same with a different attack name substituted in, you have memorised vocabulary, not met the objective. That test — could I handle the scenario version of this line? — is the everyday use of the document.
The objectives tell you what can be tested, never how well you currently perform under exam conditions and never which resources to use. For the full preparation workflow around this method, see the dedicated guides on how to prepare for CompTIA Security+, how to prepare for CompTIA A+ and how to prepare for CompTIA Network+ — each builds a resource plan on top of the objective-mapping approach described here. And for exam-day logistics, scoring scales and retake rules, comptia.org's test-policy pages are the authoritative source.
Treat the objectives PDF as a living checklist — extracted, rated, scheduled by weight-times-weakness, and re-rated until every scenario row has hands-on proof behind it — and you convert a free document into the backbone of your entire preparation. The habit transfers: every CompTIA exam you take after this one, from Network+ to CySA+, publishes its objectives the same way, and the twenty minutes you now spend reading verbs before topics will keep telling you exactly what kind of studying each certification really demands.
