ExploreAbout this exam
CompTIA A+ is CompTIA's entry-level certification for people beginning a career in information technology support. CompTIA describes it as covering "core IT support and troubleshooting" - the day-to-day work of keeping end-user devices, networks, and user accounts running. It is aimed at aspiring help desk technicians, desktop support and field service specialists, career changers, and students in secondary and higher-education technology programs. The exam spans five broad areas: mobile devices, networking, hardware, virtualization and cloud computing, and hardware and network troubleshooting. Candidates should expect a mix of terminology, component identification, configuration tasks, and scenario-based troubleshooting in which you select the most likely cause or the next best step. Preparation usually combines a structured course or self-study guide, hands-on practice with physical or virtual machines, and practice questions that force you to explain why each wrong answer is wrong. CompTIA's own online test-prep product is CertMaster Practice; many candidates pair it with lab work. Confirm current objectives, pricing, and scheduling directly with CompTIA, because these details change between revisions.
What you'll study
About CompTIA A+ preparation
What does CompTIA A+ actually certify?
It certifies core IT support and troubleshooting skill, per CompTIA's own description. In practice that means installing, configuring, and repairing end-user devices, connecting them to networks, supporting mobile hardware, working with virtualization and cloud services, and diagnosing faults with a structured troubleshooting method. It is an entry-level support credential rather than a networking or security specialty.
Who should take the A+ exam?
People entering IT support: help desk, desktop support, field service, and repair roles, plus career changers and students in technology programs. CompTIA makes exam vouchers and CertMaster Practice purchasable by eligible K-12 schools, educators, and students in the CYBER.ORG network, so secondary students are an explicit audience for the voucher program.
How many exams are there, and how many questions and how much time?
The source material available here does not state the number of exams, the item count, or the time limit, and CompTIA revises these details periodically. Check the official CompTIA A+ exam page and the downloadable exam objectives before you schedule. Do not rely on figures from older study guides or forum posts.
What score do I need to pass, and what does the exam cost?
Passing scores and exam fees are set by CompTIA and are not given in the material this page is based on. Look them up on CompTIA's official exam page and store at the time you book, since regional pricing differs and education promo codes can change what you pay.
How difficult is A+?
The difficulty is mostly volume rather than depth. A wide vocabulary of hardware, networking, mobile, cloud, and support concepts has to be solid, and many questions are written as scenarios instead of definitions. Candidates with repair or help desk experience usually find it manageable; complete beginners typically need consistent study plus lab practice over several months.
Can I retake the exam if I fail?
Retake rules and any waiting period between attempts are CompTIA policy and are not stated in the sources used for this page. Confirm the current policy on CompTIA's certification or store pages before you buy a voucher, and budget for a second attempt if vendor exams are new to you.
How long is the certification valid?
Validity periods and continuing-education requirements are set by CompTIA and are not given in the sources here. Because CompTIA periodically revises both exam objectives and recertification rules, check your certification status in your CompTIA account and read the current renewal policy rather than a third-party summary.
What study order works best?
Start with hardware and mobile devices so you can picture the components, then networking, then virtualization and cloud, and finish with troubleshooting, which assumes the other four areas. Add hands-on labs throughout: build or tear down a PC, set up a small network, configure a hypervisor. Save practice questions for once the vocabulary is stable.
What are the most common failure modes?
Memorizing acronyms without the underlying concept, skimming troubleshooting methodology and jumping straight to a fix, and never practicing performance-based tasks with real interfaces. Practicing scenario questions until you can name why each wrong option is wrong pays off, and verifying exam logistics early prevents a scheduling surprise from wrecking a study plan.
Is A+ enough on its own to get a support job?
It is a first credential, not a guarantee. Employers hiring for support roles usually want a certification plus evidence of hands-on ability such as a home lab, a repair project, or a student help desk role, along with customer-facing communication skills. Documenting lab work alongside the certification makes a real difference in an entry-level search.
