The CompTIA A+ certification is the most widely recognised entry-level credential in the information technology industry. It validates foundational knowledge across hardware, software, networking, security, and troubleshooting, and it is the standard starting point for anyone pursuing a career in IT support, help desk roles, or technical field service. The certification is vendor-neutral, meaning it does not tie your knowledge to any single manufacturer or platform, which makes it applicable across a broad range of work environments. Employers across government agencies, managed service providers, corporate IT departments, and healthcare organisations consistently list A+ as a preferred or required qualification for entry-level technical positions.
The current version of the exam consists of two separate tests: Core 1, also known as 220-1101, and Core 2, also known as 220-1102. 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 is the most well-known and widely recommended free resource for CompTIA A+ exam preparation in the entire IT certification community. Jason Dion and other instructors have produced paid content, but Professor Messer’s website offers a genuinely free and complete set of study materials that covers every exam objective for both Core 1 and Core 2. The website provides free video training courses that walk through every topic on the exam in structured, objective-by-objective lessons. These videos are available on both the Professor Messer website and YouTube, and they are updated with each new version of the exam to ensure the content stays aligned with what CompTIA is currently testing.
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
Several major online learning platforms offer free A+ preparation courses that require no payment to access. Alison, a free online learning platform, hosts CompTIA A+ preparation courses that cover core hardware and software concepts and award a certificate of completion that can be shared on LinkedIn. While Alison’s certificate of completion is not the same as the actual CompTIA credential, the courses provide structured learning paths with quizzes and assessments that help reinforce knowledge as you progress through the material. The platform is entirely free to use, with paid options available only for printed certificates, which are not necessary for exam preparation purposes.
GCFGlobal, run by the Goodwill Community Foundation, offers free technology courses that cover computer basics, hardware fundamentals, and operating system navigation that directly support A+ preparation, particularly for candidates who are newer to working with computers at a technical level. Coursera and edX both offer free audit options for some technology courses that include A+ relevant content, allowing learners to access video lectures and reading materials without paying for graded assignments or certificates. Khan Academy’s computing courses cover foundational concepts in binary, networking, and internet infrastructure that build the theoretical background needed for certain A+ exam topics. Using a combination of these platforms alongside Professor Messer creates a multi-format learning experience that reinforces material through varied presentation styles.
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 also publishes free exam preparation tips, sample questions, and career pathway guides on its website. The CertMaster Learn platform offers a free trial that gives temporary access to interactive study content including lessons, assessments, and performance tracking. While the full CertMaster Learn subscription is a paid product, the trial period provides enough access to evaluate the quality of the material and work through at least some of the content at no cost. 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
The IT certification community on Reddit is one of the most active and practically useful free resources available to A+ candidates. The subreddit dedicated to CompTIA, along with the broader IT careers and network engineering communities, contains thousands of posts from candidates who have recently passed the exam sharing their study strategies, the resources they found most helpful, the topics they found most difficult, and the specific areas where their preparation fell short. Reading through recent pass posts from the last three to six months gives you a realistic picture of what the current version of the exam emphasises and which topics tend to generate the most questions during actual test sessions.
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
Practice tests are an essential component of A+ preparation because they simulate the conditions of the actual exam and identify specific knowledge gaps that need additional study attention. Several websites offer genuinely free A+ practice questions without requiring payment or subscription. ExamCompass is one of the most commonly recommended free practice test resources in the A+ community, offering hundreds of questions organised by exam domain for both Core 1 and Core 2. The questions are presented in multiple choice format with immediate feedback and explanations for both correct and incorrect answers, which turns each practice session into an active learning exercise rather than just a score check.
CompTIA’s own website provides a small number of official sample questions for each exam, which are valuable because they reflect the exact style, terminology, and difficulty level of actual exam questions. Quizlet hosts numerous A+ flashcard sets and practice question collections created by the community, and while the quality varies between individual sets, the highest-rated sets are generally accurate and well-organised. Jason Dion’s website and Udemy page offer limited free sample questions from his paid practice test packages, giving you a taste of professionally written exam-style questions at no cost. 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
Public libraries are a frequently overlooked source of free A+ training material that can significantly supplement online video content. Most public library systems provide cardholders with free access to LinkedIn Learning, formerly known as Lynda, through a partnership programme that requires only a valid library card to activate. LinkedIn Learning hosts a comprehensive CompTIA A+ preparation course that covers both Core 1 and Core 2 in structured video format with instructor-led lessons, quizzes, and exercise files. This is a professionally produced course that would cost money if accessed directly through a LinkedIn subscription, but it is available at no cost through the library card access programme in many cities and counties.
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
Having access to free resources is only valuable if you use them systematically within a structured study schedule that ensures complete coverage of the exam objectives before your test date. The most effective approach is to use the official CompTIA exam objectives document as your study roadmap and work through each domain and subdomain in order, matching each objective to the corresponding video lesson, textbook chapter, or online course module from your chosen free resources. Tracking your progress against the objectives document gives you a clear picture of how much of the syllabus you have covered and how much remains, which prevents the common mistake of spending excessive time on familiar topics while neglecting difficult or unfamiliar ones.
A realistic study schedule for a candidate with limited prior IT experience typically spans eight to twelve weeks of consistent daily study, with more experienced candidates able to prepare in four to six weeks. Dedicating one to two hours per day to structured study covering new material through video or reading, followed by short practice quizzes to reinforce retention, builds knowledge progressively without overwhelming your other commitments. Reserving the final two weeks before the exam for intensive practice testing and review of weak areas is the standard approach recommended by most successful candidates. Using free resources strategically within this kind of structured timeline transforms a collection of scattered free materials into a coherent and effective preparation programme that can produce a passing score without spending a single dollar on training.
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 and operating system topics, free virtualisation tools such as Oracle VirtualBox and VMware Workstation Player allow you to install and configure Windows 10, Windows 11, and Linux distributions in virtual machines on your existing computer at no cost. Practising tasks such as partitioning drives, configuring user accounts, adjusting system settings, troubleshooting boot errors, and navigating the command prompt builds the procedural familiarity that exam questions about these topics test. Combining regular hands-on practice with your free video and reading study creates the kind of multi-modal learning experience that produces deep, durable knowledge rather than surface-level familiarity that fades quickly under exam pressure. Candidates who can connect what they see in a video to what they have physically done on a machine retain that knowledge far more reliably than those who studied only through passive consumption of online content.
Conclusion
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.
Several employer tuition and certification reimbursement programmes cover CompTIA A+ exam costs for employees who pass, meaning the cost is only temporary if you are currently employed and willing to seek reimbursement after earning the credential. Veterans and active military personnel have access to the MyCAA scholarship and GI Bill benefits that cover CompTIA certification exam costs. Non-profit organisations such as Per Scholas, Year Up, and NPower provide free technology training programmes that include exam vouchers for qualifying participants. CompTIA itself periodically offers promotional discounts on exam vouchers through its website and partner channels. Combining free training resources with one of these voucher access pathways makes it genuinely possible to earn the A+ certification with no out-of-pocket expense, which removes the financial barrier entirely for candidates who are willing to invest the time and effort that quality preparation requires.
