Free CompTIA A+, Network+ and Security+ courses

CompTIA's certifications are where many IT careers start: A+ for support work, Network+ for networking, Security+ for the security roles that ask for it by name. Each exam has a free, complete video course on YouTube, and Professor Messer's are the ones most people are pointed to. His courses are built from short videos, one exam objective each, while other teachers record a few long sessions. Either way, the length of the course is the number that tells you when to book the exam.

The numbers next to each course are live totals from the playlist itself, ranked longest first. Click one to see every video, tick off what you've watched, and get a finish date.

How to choose

The usual order is A+, then Network+, then Security+. A+ is two exams, Core 1 (220-1201) and Core 2 (220-1202), and you need both.
Short videos or long sessions: Professor Messer's courses are made of short videos that map one-to-one to the exam objectives, which makes them easy to revise from. BurningIceTech and Certify Breakfast teach in long sessions, which suits a first pass.
Check the exam code. CompTIA replaces each exam every few years. Make sure the code in the course title matches the exam you are booking on CompTIA's site.
