Locked In: IT Support Prep

Locked-In is a bite-sized study companion for the CompTIA A+ certification — both Core 1 (220-1201) and Core 2 (220-1202). Built for people who study in 10-minute windows on the train, on lunch, or between meetings — every lesson is short, focused, and ends with a quick-check so you know what stuck.
