Free study resources
Handed a CompTIA course with no lab and no curriculum, on a Chromebook cart, old PCs, or nothing, with a 50-minute period? Here is what is genuinely free, what it costs beyond free, and what each one lacks. Every tool below carries a public link and the date we last read its own page, so you can check it yourself.
These are hands-on procedures and study tools that teach the job skill behind an objective. They are not exam questions and not a score predictor, and nothing here comes from any exam. This guide gets you the knowledge the certification expects; it does not get you the job, and practice is not the same as on-the-job experience.
Each entry is read from the provider's own public page. Nothing is inferred from silence, and forum opinions are left out.

What RTJ gives you free
Free hands-on procedure labs are in development and will be added to this page, free, when they are ready. They are not available yet.
No credit card is required. RTJ is an independent study platform and is not endorsed by or affiliated with CompTIA. CompTIA's policy on unauthorized training materials is on its own site. Provider and product names belong to their respective owners.
