DUSÇöz

A free, independent question bank for dentists in Türkiye who are preparing for the Dental Specialty Exam (DUS). The product is in Turkish; this page is an overview in English.

What it is

The DUS is the national exam, run by ÖSYM, that decides who is placed into dental specialty training in Türkiye. DUSÇöz is where candidates practice for it: topic tests, full mock exams, a mistake notebook that brings wrong answers back, and an AI study assistant.

It is live at duscoz.com and works in any browser. It can also be added to a phone's home screen, so there is no separate app store download.

What you can do

Practice by branch. 1,500+ questions across 16 branches (8 basic sciences, 8 clinical sciences), as topic tests or a mixed quick-solve.
Learn from every answer. Each question has a reasoned explanation, unlocked with a free account.
Mock exams. 120 questions in 150 minutes, in the format of the real DUS.
Mistake notebook and spaced repetition. Wrong answers come back after 1, 3, 7 and 15 days. Short flashcards are included.
Dusky, the AI study assistant. Explains the logic behind a question and points to your weakest branch.
Friendly competition. 10-question duels with friends, weekly leagues, daily streaks and goals.
Free guide pages and tools, no account needed: a net-score calculator, an exam calendar with a countdown, a weekly study-plan builder and a branch map (in Turkish).

Try it without signing up

Anyone can solve practice questions without an account; guests get up to 10 questions per test. Free accounts are created with a Google account or a passkey. Everything is free at the moment.
