A preparation programme that advances Mathematics, Geometry and Numerical Reasoning in parallel throughout, built on live lessons and systematic mock-exam analysis.
Mathematics + Geometry + Numerical Reasoning
Language of instruction: Turkish, English, Persian (Farsi)
There is a single programme; students follow the lessons in whichever of the three languages they prefer. The choice changes neither the lesson count, the calendar nor the fee, and it is asked in the enrolment form after payment.
54 live lessons = 48 main teaching lessons (72 hours) + 6 live mock-analysis lessons (9 hours)
Weekly Schedule
During the main teaching phase there are four lessons a week — 6 hours of live instruction. On Saturdays there is a 15-minute break between the two lessons.

Main Teaching Phase
The three areas run in parallel across the programme rather than in separate blocks. Open any week to see the date, day, time, subject area and sub-topics.
Mock Exam Camp
After the main phase: two full TR-YÖS mock exams and one live analysis lesson every week — 12 mock exams and 6 live lessons in total.

Final Analysis – Mock Exams 11–12 and Exam Strategy
The teacher does not simply work through all 80 questions from the start. Each lesson is built around what the performance data actually shows.
Between Wednesday, 7 April 2027 and Sunday, 11 April 2027 there are no live lessons, no compulsory mock exams and no new topics. This period is reserved for each student's own final revision: their error log, mistakes from earlier mocks, question types they find hard, formulae and short notes, and their personal strategy.
What's Included
There is no extra charge for the question bank or the mock exams — all of it is covered by the group course fee.
Who It's For
This programme is not designed to teach mathematics from scratch. It is built for students who already have secondary-school mathematics behind them, know the fundamentals of geometry, and are preparing seriously for TR-YÖS with a high score in mind.
The academic approach: adapt the mathematics a student already has to the way TR-YÖS asks questions, build problem-solving speed, teach the Mathematics and Geometry techniques specific to this exam, and develop strong exam practice in the Numerical Reasoning section in particular.
Definitions of natural and rational numbers, what an acute or obtuse angle is, what a triangle is, the four operations, very basic equation solving and very basic geometric definitions.
Term and Enrolment
The main phase begins on Tuesday, 1 December 2026 and finishes on Tuesday, 23 February 2027. The mock exam camp runs from Saturday, 27 February 2027 to Tuesday, 6 April 2027. Classes are capped at six students.
The programme calendar has been planned around a target exam date of 12 April 2027. Dates will be updated as needed once ÖSYM publishes its official 2027 exam calendar.

"As an international student, the YOS exam felt overwhelming at first. TestPrep's tutors not only prepared me for the Math and IQ sections but also guided me through the entire university application process. I was accepted to Istanbul University's Medical Faculty. I couldn't have done it without their support."

Detailed Information
The YOS (Foreign Student Examination) exam is the primary pathway for international students seeking admission to Turkish universities. Each university designs and administers its own YOS exam, typically consisting of Mathematics, Science (Physics, Chemistry, Biology) and IQ (Abstract Reasoning) sections. Scoring well on the YOS is essential for gaining admission to competitive programs such as Medicine, Engineering and Law at Turkey's top universities.
TestPrep's YOS program is specifically designed for international students. We provide comprehensive preparation across all three sections with special emphasis on the IQ component, which is unique to the YOS format. Our tutors have deep knowledge of each university's exam format and question styles, allowing us to create targeted preparation plans for your specific university choices.
Our students have been accepted to Turkey's most prestigious institutions including Istanbul University, Ankara University, Hacettepe University and Istanbul Technical University. We support you not only with exam preparation but also with university selection, application procedures and program matching to ensure you find the best fit for your academic goals.

Felipe Montalvo
The group never had more than six students, so it was easy to stay involved. I finally understood what was going wrong in Time Management. My preparation became much more regular and easier to track. A big thank you to my tutor for all the support :)
Felix Schmitz
We weren't sure whether online lessons would be effective. We were able to follow the mock results regularly. The plan was adjusted when school exams became busy. The tutor's close attention to weaker areas gave us confidence. It was good to see confidence returning over time. We were pleased with the support we received.
Madison Chandler
Over time, IQ & Logic became one of the most organized parts of my YÖS / TR-YÖS preparation. I became much more comfortable asking questions in class.
Shota Takeuchi
Our child wasn't sure how to organize the preparation for YÖS / TR-YÖS. Preparation looked calmer and more organized closer to the exam.
Hina Maeda
The YÖS / TR-YÖS format felt unnecessarily confusing at first. My confidence improved along with the results.
Mika Valdez
I was taking Mathematics at school, but getting used to the exam questions took time. I started noticing the reason for a mistake much faster.
