DEYOS exam is conducted on two languages (Turkish and English) and consists of 80 multiple choice questions. The test duration is 120 minutes.
The content of exam consists of mathematics, physics, chemistry, biology, history, geography and general culture courses.
Exam evaluation is done by taking into account of only the right answers over 100 (one hundred) points, wrong answers are not taken into account (the questions that the candidate answers more than one are considered wrong). (Wrong answers are ineffective in score calculation, so answering all questions will be in favor)
Number of correct answers for each course are used to calculate the standart deviation and the mean and by setting the average of the distribution to 50 and the standard deviation to 10 the standardization process is applied for the course. Standardized values are multiplied by 1.25 and a single DEYOS score is calculated for each candidate.
