YDSAce

Thousands of real YDS-format questions, smart spaced repetition, and full mock exams. Learn with clear explanations, build a streak, and be exam-ready.

YDSAce is a focused prep app for Türkiye's state English proficiency exam, the YDS (and YÖKDİL). Everything you need, nothing you don't — four tools designed around how serious candidates actually study.

EXAM-FORMAT QUESTION BANK Multiple choice, paragraph completion, cloze tests, vocabulary, and word formation — all written in the real YDS format. New sets added regularly, so you never run dry. Thousands of questions across B1, B2, and C1 levels.

SMART SPACED REPETITION A Leitner box system reinforces what you forget and skips what you've mastered. Stop wasting time on what you already know.

FULL MOCK EXAMS Timed B2 and C1 mock tests that simulate the real YDS, end to end. See your weak areas after every attempt.

A CLEAR EXPLANATION FOR EVERY QUESTION Every question comes with a clear Turkish explanation — why the right answer works and why the distractors don't. Learn the reasoning, not just the answer.

STAY MOTIVATED Daily streaks, a weekly leaderboard, and achievement badges. Stay motivated alongside other candidates working toward the same goal.

PRIVACY-RESPECTING No ads, no third-party tracking, no selling your data. We built YDSAce the way we'd want our own apps built.

TURKISH UI, ENGLISH EXAM CONTENT Exactly the way you'll see it on test day. Every question reviewed against real YDS standards.
