CompTIA A+ is a widely used vendor-neutral credential for entry-level technical support skills, including hardware, operating systems, networking, security and troubleshooting. It can help an applicant demonstrate a common foundation, but it is not a universal hiring requirement or a promise of employment. Start by comparing the tasks in actual support-job postings with the current A+ objectives. That tells you whether the credential and a free-study plan suit the role you want.
CompTIA A+ V15 uses two exams: Core 1 (220-1201) and Core 2 (220-1202). The earlier 220-1101 and 220-1102 series is retired; candidates should use the current V15 exam objectives and book both cores from the same version. Core 1 covers mobile devices, networking technology, hardware, virtualisation and cloud computing, and hardware and network troubleshooting. Core 2 covers operating systems, security, software troubleshooting, and operational procedures. Both exams must be passed to earn the full certification. Understanding the scope of what these two exams test is the starting point for identifying which free training resources will cover the material you need most, and it helps you build a structured study plan rather than consuming resources randomly without a clear sense of progress or direction.
Professor Messer Free Resources
Professor Messer offers a free, version-specific A+ video course for the currently published 220-1201 and 220-1202 exams, with study-group replays and quizzes. His course index separates free videos from optional paid notes or assessment packages. Check the exact exam codes and published coverage before deciding which lessons to follow; that distinction matters more than claims that any instructor is the most popular in the entire community. The issuer, CompTIA, remains authoritative for the tested objectives.
In addition to the free video courses, Professor Messer provides free study groups that are recorded and made available as audio podcasts, which means you can consume the content while commuting, exercising, or doing other tasks. The website also offers course notes in PDF format that summarise the key points from each video section, giving you a compact reference document that pairs well with the videos for revision. While Professor Messer does sell practice exam packages separately, the free content alone is substantial enough to build a solid knowledge foundation. Many candidates who passed A+ on their first attempt have credited Professor Messer’s free videos as their primary study resource, which speaks to the quality and completeness of what is available at no cost.
YouTube Channels Worth Watching
Beyond Professor Messer, YouTube hosts a wide range of free A+ training content from instructors and IT professionals who have created detailed tutorial series covering the full exam syllabus. Channels such as PowerCert Animated Videos are particularly useful for visual learners because they use animation and diagrams to explain hardware components, networking concepts, and operating system functions in ways that are easier to retain than text-based explanations alone. The visual format is especially helpful for topics such as motherboard components, network topologies, RAID configurations, and virtualisation concepts, where seeing the relationships between components makes the material much more intuitive than reading about it.
Other YouTube channels worth regularly consuming during A+ preparation include Crosstalk Solutions for networking fundamentals, ITPro.TV clips available on YouTube for structured lesson-style content, and the CompTIA official YouTube channel itself, which publishes exam tips, study guides, and introductory content that directly reflects the objectives being tested. The advantage of using YouTube as a study platform is the ability to adjust playback speed, revisit specific sections instantly, and access content on any device without any account creation or subscription. Building a custom YouTube playlist that organises free A+ content by exam objective turns YouTube into a structured learning management system that you control entirely at no cost.
Free Courses On Open Platforms
Open-learning platforms can supplement A+ preparation, but free access and credential terms differ by course, region and enrollment period. An Alison technology course, for example, may teach useful hardware or operating-system concepts without mapping every lesson to the current 220-1201 or 220-1202 blueprint. A completion certificate issued by a training platform is not CompTIA A+ certification. Check which lessons, assessments and certificates are actually included without payment before committing study time.
General computer-literacy courses from GCFGlobal or other educational platforms can help learners practise file management, operating-system navigation and fundamental networking. Universities and course marketplaces sometimes let students audit selected technology material, but audit rights, access duration and graded work vary. Use these courses to repair prerequisite gaps; do not assume a broad computing syllabus teaches the diagnostic decisions and exam-specific operational procedures that CompTIA A+ assesses.
CompTIA Official Free Content
CompTIA itself provides a range of free resources directly on its website that candidates often overlook while searching for third-party training. The official exam objectives document for both Core 1 and Core 2 is available as a free download from the CompTIA website and is one of the most important documents any A+ candidate can have. This document lists every single topic that the exam can test, organised by domain and subdomain, and it is the authoritative source for building a study checklist. Any training resource, whether free or paid, should be evaluated against the official objectives document to confirm that it covers the full scope of the exam rather than only selected topics.
CompTIA publishes official exam objectives and information about its CertMaster learning products. The availability of free samples, trial accounts and particular assessments varies by edition and date. Check the issuer’s current terms rather than assuming a specific free trial or content entitlement will be offered. CompTIA’s LinkedIn page and official blog regularly publish study tips, exam update announcements, and domain-specific breakdowns that can supplement your primary training resources. Staying connected to CompTIA’s official communications also ensures you are aware of any exam version changes or updates that might affect your preparation timeline.
Reddit And Community Study Groups
Community discussions can be useful for explaining concepts, finding lab ideas and learning how others structured their schedules. Reddit posts and chat servers, however, are not issuer announcements, and a self-reported pass story cannot establish which questions or topics will appear in your sitting. Prefer threads that cite current objectives and technical documentation. Avoid asking others to reproduce confidential examination content or using recollections of restricted questions as a substitute for learning.
Beyond reading existing posts, actively participating in Reddit study communities by asking questions and contributing answers accelerates learning considerably. Teaching a concept to someone else, even in a text post on a forum, forces you to articulate your own understanding and reveals gaps in your knowledge that passive study does not expose. Many Reddit users also form virtual study groups through Discord servers where members share notes, quiz each other, and work through practice questions together. These free community study environments provide accountability and social learning that solo study cannot replicate. The CompTIA Discord server and several A+ specific Discord communities are easily found through Reddit posts and offer channels dedicated to specific exam domains where focused discussion and peer support are available around the clock.
Free Practice Tests Available
Free A+ practice questions can provide a useful diagnostic check when their answer explanations are technically sound and their exam edition is explicit. A large number of questions or a claim that they mimic the live exam does not establish validity. Sample a few unfamiliar items, explain why each incorrect option fails and then test the underlying principle in a small lab. Do not treat repeated recognition of a familiar bank as readiness for an unknown exam scenario.
Check whether CompTIA currently publishes samples or official training materials for the specific A+ examination edition. Availability varies, and any sample is illustrative rather than a reliable prediction of live question difficulty. Community flashcards can help reinforce technical vocabulary, but popularity ratings do not establish that questions or answers match current official objectives. Check disputed claims against authoritative documentation. Third-party sample availability and licensing can change; check a provider’s current offer directly and judge question explanations on accuracy rather than promotional claims. When using any free practice test resource, treat wrong answers as study prompts rather than just failures, and research each incorrect answer until you understand not only the right answer but why the other options were wrong.
Library And Institutional Resources
Check your local public library, community college or workforce center for technology-learning resources before buying a subscription. Some library systems offer digital-learning platforms or technical ebooks, while others do not; access usually depends on residence, card eligibility and the library’s current licensing agreements. Ask whether any available A+ course matches the 220-1201/220-1202 objectives and whether hands-on exercises or practice assessments are included. Borrowing an old guide can still teach foundations, but it cannot substitute for an edition-specific coverage check.
Many library systems also provide free access to O’Reilly Learning, which hosts technical books, video courses, and interactive labs relevant to A+ preparation. Physical library branches typically hold copies of CompTIA A+ study guides from major publishers such as Mike Meyers, Mike Chapple, and David Seidl, which are comprehensive textbook-style references that cover every exam objective in thorough detail. Borrowing these books from the library provides access to premium study material without any purchase cost. Community colleges and workforce development programmes in many regions also offer free or heavily subsidised A+ preparation courses as part of their career retraining initiatives, particularly for unemployed or underemployed adults seeking to enter the technology workforce. Checking with your local community college or workforce development centre is worth doing early in your preparation process.
Building A Free Study Schedule
Free training is useful when it can be mapped to the current Core 1 and Core 2 objectives and supplemented with safe hands-on practice. Use the official CompTIA objectives as a checklist, recording which topics you can explain and demonstrate, where a free course leaves gaps, and which tasks require equipment or a virtual lab. Completing a video playlist or ticking every syllabus heading does not establish exam readiness; test unfamiliar topics through troubleshooting scenarios and revisit errors before booking.
An A+ preparation plan should start with a diagnostic review of the current objectives and the learner’s practical experience. Set small, repeatable sessions for troubleshooting, operating-system tasks, networking and security, then allocate more time to areas where the learner cannot yet explain a decision or complete a lab safely. The time required varies widely, and a fixed number of weeks or hours is not evidence that someone is ready to pass. Use exam-version-specific practice scenarios to expose remaining gaps and verify any deadline, voucher or retake requirement with CompTIA before scheduling.
Hands On Practice At Home
One aspect of A+ preparation that free online resources cannot fully replace is hands-on experience with actual hardware and software. The exam tests practical knowledge of tasks such as installing RAM, replacing hard drives, connecting peripherals, configuring operating system settings, troubleshooting network connectivity, and identifying cable types and port standards. Gaining this experience does not require spending money on new equipment. Older computers that are no longer in daily use, whether personal devices, donated machines from family members, or inexpensive secondhand computers purchased from thrift stores or marketplace listings for very little cost, provide excellent hands-on practice platforms for hardware tasks.
For software work, an owned spare machine or an isolated virtual machine lets you practise account management, operating-system settings and recovery without changing a production device. Oracle VirtualBox and VMware Workstation Pro are potential desktop virtualization options; Broadcom discontinued new downloads of Workstation Player in 2024 and made the Pro product free to use. Use supported guest operating systems with valid licenses. Windows 10 Home and Pro passed their normal support deadline in October 2025, so a legacy Windows 10 lab must be isolated, clearly labeled as historical, and not treated as secure daily-use practice. Keep a snapshot, record the starting configuration and test restoration after risky exercises.
Earning the A+ certification ultimately requires paying for and passing the two official CompTIA exams, but there are several legitimate ways to reduce or eliminate this cost entirely for qualifying candidates. CompTIA offers exam voucher discounts through its Academic Marketplace for students enrolled in educational programmes, and many workforce development and job training programmes provide exam vouchers as part of their free training services. Checking with your local workforce development office, community college, or state employment agency about available technology certification funding programmes is worth doing before assuming you need to pay full exam price.
Employer reimbursement and workforce grants can reduce A+ testing costs, but eligibility, approvals, funding limits and covered products vary. Military OneSource’s SpouseWorks Scholarship (formerly MyCAA) serves eligible military spouses, not all veterans or active-duty personnel by virtue of service alone; GI Bill education benefits follow separate VA rules and approved-program conditions. Nonprofits and career-retraining organizations may include vouchers in specific cohorts, but a provider name is not proof of a current no-cost seat. Before relying on funding, get the eligibility, covered exam, disbursement and refund conditions in writing. Genuine CompTIA certification preparation may be free even when the two required issuer examinations are not.
