This is a role course, not a question bank. It teaches what a first-line IT support technician actually does, organised around the knowledge areas the CompTIA A+ objectives cover: hardware and peripherals, operating systems, networking, security basics, mobile devices and, above all, a repeatable troubleshooting method and the customer skills that turn a fix into a good outcome. Every lesson ends with an action step that builds a home lab, a documentation habit or a portfolio piece.

For career changers entering IT, help-desk staff formalising what they know, and anyone preparing to sit A+ who wants the understanding behind the objectives rather than memorised answers.
