FAQ
YOS Prep — Frequently Asked Questions
The questions students ask most about YOS preparation.
No. The TR-YOS has two tests in one 100-minute session: the Numerical Aptitude Test (40 questions) and the Basic Mathematics Test (40 questions). There are no biology, chemistry or physics questions. Some universities run their own entrance exams, and those can include other subjects.
The main teaching phase begins at 19:00 on Tuesday, 1 December 2026 and finishes on Tuesday, 23 February 2027. A 6-week mock exam camp then runs from Saturday, 27 February 2027 to Tuesday, 6 April 2027, which is the date of the programme's final live lesson.
54 live lessons and 81 hours of live instruction in total: 48 lessons (72 hours) in the main teaching phase and 6 lessons (9 hours) of live mock analysis during the camp. Each lesson lasts 90 minutes.
During the main phase there are four lessons a week: Tuesday and Thursday 19:00-20:30, and Saturday 13:00-14:30 and 14:45-16:15, with a 15-minute break between the two Saturday lessons. During the mock camp the exams fall on Saturday and Sunday, and the live analysis lesson is on Tuesday 19:00-20:30. Tuesday 9 March 2027: no lesson; the make-up lesson (analysis of mock exams 3–4) is on Friday 12 March 2027 at 19:00.
Lessons can be followed in Turkish, English or Persian (Farsi). There is a single programme — your choice of language does not change the lesson times, the calendar or the fee. The Persian class runs only if enough students enrol. If it doesn't, students who chose Persian join the English class.
12 full TR-YOS mock exams and the TR-YOS question bank are included in the course fee, along with lesson materials and homework. None of it carries an extra charge.
There is no lesson on Thursday, 31 December 2026 or Friday, 1 January 2027. The make-up for the Thursday lesson is on Tuesday, 23 February 2027 at 19:00, which is why the main phase closes on that day.
Yes. The group course fee can be paid in full or in two instalments. Payments are taken by credit or debit card through Stripe.
No. The programme calendar is planned around a target exam date of Monday, 12 April 2027; this is not a date ÖSYM has officially announced. Once ÖSYM publishes its official 2027 exam calendar, the dates will be updated as needed while the academic structure stays the same.
A group course takes 24 students, taught in classes of at most 6 because the group is split by level. Lessons are live and online, and every lesson is recorded; each recording stays available for 14 days from the lesson date.
The money-back guarantee covers live lessons. If you are not satisfied after your first private lesson, we refund your payment in full. On a group course, the same applies to the lessons held in the first week. The question bank and practice tests are not part of it.
No. Practice tests and question banks are digital products that open on your account as soon as you buy them, so they can't be withdrawn from or refunded.
Lessons cancelled less than 3 hours before the start count as taken and are not refunded. A lesson that has not been paid for 3 hours before it starts is cancelled automatically.

What the analysis lessons prioritise
- questions answered incorrectly
- questions left blank
- questions most students struggled with
- questions that took far too long
- questions with a shorter available solution
- recurring error patterns
The teacher does not simply work through all 80 questions from the start. Each lesson is built around what the performance data actually shows.
The Final Stretch Before the Exam
Between 07/04/2027 and 11/04/2027 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
Included in the Group Course Fee
- 54 live lessons
- 81 hours of live instruction
- A choice of Turkish, English or Persian as the language of instruction (Persian: if enough students enrol)
- TR-YOS question bank
- Lesson materials
- Homework
- 12 full TR-YOS mock exams
- 6 live lessons analysing the mocks and working through the questions
- Analysis of incorrect and unanswered questions
- Exam strategy
- Time-management practice
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
Who Is This Programme 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-YOS with a high score in mind.
The academic approach: adapt the mathematics a student already has to the way TR-YOS 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.
Introductory topics the lessons do not dwell on
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.
About the exam date
The programme calendar has been planned around a target exam date of 12/04/2027. Dates will be updated as needed once ÖSYM publishes its official 2027 exam calendar.
Exam Sittings
TR-YOS, TR YOS 1 and TR YOS 2: A Complete Guide
Everything you need to know about the centralised YOS administered by ÖSYM, Türkiye's Measuring, Selection and Placement Center. Choosing the right YOS prep course starts with understanding the exam structure and the calendar.
TR-YOS (Centralised YOS)
Mandatory From 2024The centralised foreign student examination administered nationally by ÖSYM. From 2024 onward, the vast majority of Turkish state universities accept TR-YOS scores in place of their own institution-specific YOS sittings. It is now the standard, single-source admissions exam for international undergraduate applicants to Türkiye.
Administered nationally by ÖSYM, twice per year
The question booklet is in Turkish, with German, English, French, Russian and Arabic translations inside it
The most widely accepted exam for state universities
Scores remain valid for 2 years
Wrong answers cost marks: in each test, four wrong answers cancel one right answer
Exam Structure
Numerical Aptitude TestWeight 0.45

Basic Mathematics TestWeight 0.55

Total: 80 questions100 minutes (one session)
TR YOS 1 (Spring sitting)
Twice a YearThe spring sitting of TR-YOS, typically held in April or May. Students may use one of their two annual sitting slots here. Spring scores are accepted for that same calendar year's autumn university applications, so this is the right window for candidates who want to start university that September.
Sat in April or May
Ideal for starting university in the autumn of the same year
Identical format and difficulty to TR YOS 2
Scores valid for the same year's applications
Allows an early-application head start

TR YOS 2 (Autumn sitting)
Second ChanceThe autumn sitting of TR-YOS, typically held in September or October. It serves as a second chance for candidates whose TR YOS 1 score fell short or who skipped the first sitting. Autumn scores can also be carried into the following year's application cycle, providing strategic flexibility.

Numerical Aptitude Test
Numerical Aptitude Test: The Question Types We Practise
The Numerical Aptitude Test is one of the two tests in TR-YOS: 40 questions, with its standard score counting for 0.45 of the result. Inside our YOS private tutoring we teach a dedicated strategy and a set of solving techniques for every question type below.
Moderate–Hard
Number Series
Spotting the missing element in arithmetic, geometric and mixed numerical sequences
Moderate
Letter Series
Pattern and rule deduction based on alphabetic position
Moderate–Hard
Visual Pattern Recognition
Predicting the next figure in a visual sequence
Moderate
Analogies
Identifying relationships between concepts and forming matched pairs
Hard
Spatial Reasoning
Mentally rotating and folding three-dimensional objects
Hard
Logical Deduction
Drawing conclusions from given premises and judging truth values
Critical Tip for the Numerical Aptitude Test
This test does not reward memorisation — it tests pattern recognition and logical thinking, both of which are trainable with consistent practice. Inside our YOS prep course we systematically build these skills with a minimum of 50 questions a week. Because wrong answers cost marks, we also practise knowing when to leave a question blank.
Basic Mathematics Test
Basic Mathematics Test: What We Cover in Lessons
The 40-question Basic Mathematics Test carries a weight of 0.55, the larger share of the TR-YOS score.

Maths Strategy in YOS Private Tutoring
In the TR-YOS score the Basic Mathematics Test (weight 0.55) counts for more than the Numerical Aptitude Test (0.45). In our YOS private tutoring we build a fully personalised curriculum sized to the student's current level; a strong foundation in algebra and functions is the key to progress in maths.
What is the YOS Exam and How Should You Prepare?
YOS (the Foreign Student Exam) is the standard examination used to admit foreign nationals to Turkish universities. From 2024 onward, the centralised TR-YOS administered by ÖSYM is accepted by the vast majority of Turkish state universities. It is sat twice a year — as TR YOS 1 in spring and TR YOS 2 in autumn — giving each candidate two scoring opportunities per cycle.
What Does YOS Success Actually Require?
A successful YOS prep course prepares for both tests: Numerical Aptitude and Basic Mathematics. Each has 40 questions; Basic Mathematics counts for 0.55 of the score and Numerical Aptitude for 0.45. Because wrong answers cost marks (in each test, four wrong answers cancel one right answer), accuracy matters as much as speed.
In maths we concentrate on algebra, functions, and limits and derivatives; in geometry on triangles, circles and trigonometry, which reward visual analysis as much as formula recall.
Advantages of YOS Private Tutoring
With YOS private tutoring, your tutor can pinpoint your weak areas and tackle them quickly. Unlike group classes, one-to-one YOS private tutoring sessions build the whole curriculum around your level and your target universities. Candidates aiming for leading universities such as Istanbul University, Ankara University, Hacettepe, Boğaziçi or METU benefit greatly from a fully personalised preparation plan.
TR-YOS vs. University-Specific YOS
Each university used to run its own YOS sitting; from 2024 onward, ÖSYM's centralised TR-YOS consolidated this into a single national exam. With TR YOS 1 (spring) and TR YOS 2 (autumn) every year, the process is now fairer and more standardised. A handful of foundation universities still run their own sittings, but the vast majority of state universities now rely on TR-YOS scores.

About YOS
Frequently Asked Questions About the YOS Exam
TR-YOS is the centralised foreign-student examination administered by ÖSYM. One 100-minute session holds two tests: the 40-question Numerical Aptitude Test and the 40-question Basic Mathematics Test (80 five-option questions in all). From 2024 onward, the vast majority of Turkish state universities accept TR-YOS scores.
TR YOS 1 is sat in spring (April–May) and TR YOS 2 in autumn (September–October). Both sittings are identical in format and difficulty. Each candidate may sit twice in a year and submit their highest score with their university applications.
Depending on starting level, 8–16 weeks of preparation is typical. TestPrep Europe's standard YOS prep course is a 12-week comprehensive programme covering both the Numerical Aptitude and the Basic Mathematics tests.
YOS private tutoring drives faster progress by zeroing in on a student's weakest areas, with the curriculum fully personalised. Group classes are more affordable and add a peer-learning dynamic. Our advisers can help you pick the format that best fits your goals and budget.
Yes. In each test the raw score is the number of right answers minus a quarter of the wrong ones, so four wrong answers cancel one right answer; a blank costs nothing. Raw scores become standard scores, weighted 0.45 for Numerical Aptitude and 0.55 for Basic Mathematics, and are scaled to a score between 100 and 500. To receive a score you need a raw score of at least 0.5 in at least one of the two tests.
The TR-YOS question booklet is in Turkish, and it also carries the questions in German, English, French, Russian and Arabic.
