CompTIA study guides

Use these to get unstuck, stay organized, and study without turning cert prep into a second job.

Best first IT cert

CompTIA A+ Complete Exam Prep

Best for: Career changers, new techs, and anyone who wants one clear path through A+ instead of a pile of random resources.

Covers 220-1101 and 220-1102 with structured notes, plain-English explanations, and a clear study path.

Security entry point

CompTIA Security+ SY0-701 Study Guide

Best for: IT support folks moving toward SOC, junior security, government contractor, or security-adjacent roles.

Cuts through the Security+ acronym soup and keeps you focused on what the SY0-701 exam actually tests.

Networking foundation

CompTIA Network+ N10-009 Study Guide

Best for: Anyone who needs networking fundamentals before security, cloud, sysadmin work, or another subnetting panic spiral.

Networking feels boring until it’s the reason you can’t troubleshoot anything. This guide gives you the path without the forum rabbit holes.

Cloud infrastructure

CompTIA Cloud+ CV0-004 Study Guide

Best for: IT pros who want cloud infrastructure fundamentals before going all-in on AWS, Azure, or whatever cert their boss just discovered.

Cloud+ isn’t the flashiest cert, but it teaches the infrastructure concepts you actually use around servers, storage, networking, and ops.

Practical skills

Linux and AI guides

Not every useful career move is another cert. Sometimes the money is in getting better at the terminal or learning how to use AI tools at work.
