Built with gratitude
hecz / study is a free, open study companion for CompTIA Security+, Network+, and A+. It was built by one person studying for the exam, and it stands entirely on the shoulders of free educators who make world-class technical training available to everyone. It will always be free — no ads, no paywall, no account required.
Professor Messer
Professor Messer runs gold-standard free video courses for CompTIA Security+, Network+, and A+. This app links practice questions back to his videos when a source match exists and sends learners to his channel and site — his content is never redistributed here.
When you miss a question, the app points you to the specific Messer video that teaches that objective. The goal is always to get you watching his course, not to replace it.

How content is made
Practice questions are generated from the publicly published CompTIA SY0-701 exam objectives and reviewed for accuracy. They are not copied from any commercial question bank.
Videos from free creators are linked to their original source — never re-hosted. Thumbnails are served directly from YouTube. When you click through, you land on the creator's own channel.
When you miss a question, the app points you to the creator's video that teaches that objective. The intent is always remediation — send you to the source, not keep you here longer.
The one thing that uses live compute
The study app — questions, flashcards, exams, FSRS scheduling, and the free browser read-aloud — is free forever and runs no AI on our side.
The one exception is the optional Voice tutor: a live spoken AI tutor that runs OpenAI's realtime model in real time. That costs real money every minute, so it is capped (30 minutes a day, 60 a month) and clearly labeled. It is free while in beta. The textbook is free; the tutor's time isn't — and we will always tell you which is which.
