About this app

YOS Exam prepares you for the mathematics section of the YÖS exam, one level at a time.

The app is built around one idea: instead of reading and forgetting, you solve. Every topic is split into levels from easy to hard, and every level is a set of ten questions. Pass a set and the next one unlocks.

■ Sections
• Mathematics
• Geometry
• IQ and reasoning
• Past exams

■ What makes it work
• A full worked solution after every question — you learn why the answer is right, not just that it is
• Proper mathematical typesetting, so formulas read exactly as they do in the book
• Levels that unlock as you go, so you always know where to start
• Your results history and best scores, kept for you
• A leaderboard where you compete with other students
• Lessons alongside each topic

■ Three languages
Interface and study content in Arabic, Turkish, and English — pick your language and everything follows.

■ Honest about coverage
The question archive keeps growing, and the app tells you plainly how many questions are ready in each topic. We do not promise numbers that are not there.

■ Free, and honest about how
The whole app is free — every question, every solution, every lesson. Nothing is locked behind a payment. Ads cover the running costs, and they stay out of your way: never on a question, never on a solution.

Your study data stays with us and is used only to keep your progress. We do not sell it.
