IT certification courses

Fourteen full courses, written lesson by lesson against each vendor's published exam objectives. Every lesson and every lab is free to read, with no account and no sign-up.

What you get for free

  • Every written lesson, mapped one-to-one to the exam objectives.
  • Every lab, with the hands-on work spelled out step by step.
  • An audio episode for each lesson, which plays inside the lesson itself.
  • Practice questions as you work through the material.

A paid tier adds the full exam simulator on the courses where it is available. Nothing is taken out of the free course to make room for it.

Not sure where to start?

If you are new to IT, start with A+ Core 1 and work through Core 2, then Network+ and Security+. If you already work in IT and want to move into security, go straight to Security+ and then CySA+.
