Basic Mathematics

What this test covers

Forty original questions across the Basic Mathematics test: number properties, fractions and powers, algebra, word problems, counting and probability, sequences and logarithms, and geometry. Each has five options, as on the real paper.

This is the half of TR-YÖS that carries more weight. ÖSYM weights Basic Mathematics at 0.55 and Numerical Ability at 0.45, so it is the better place to start.

How the timing works

On the day, both tests are in one booklet and share 100 minutes. Basic Mathematics is half the questions, so this practice gives it half the time: 50 minutes. That is its fair share, not a fixed limit you will meet in the exam hall, where you decide for yourself how to divide the time between the two tests.

Questions written from scratch

Every question here is original. ÖSYM holds the copyright to its exam questions, so none is copied and none is an official question with the numbers changed. The wrong options are built from real mistakes: the greatest common divisor where the question wanted the least common multiple, the average of two speeds instead of total distance over total time, the diameter used as the radius.

What you get afterwards

Your raw net score, correct answers minus a quarter of wrong ones, and a full review of every question, with the worked solution and the most tempting wrong answer explained.

You will not get a 100–500 score, because it cannot be calculated honestly from one attempt. ÖSYM builds it from the performance of everyone who sat the same session. How TR-YÖS is scored.

Before you start

Set aside 50 minutes without interruption, with a pencil and blank paper. Do not use a calculator. If you close the tab the session is kept, but the clock keeps running, as it would in the exam hall.
