The first number that measures your performance in YKS is your net. It is your correct answers minus one quarter of your wrong answers. Questions you leave blank neither raise nor lower it.
The formula
Net = correct − wrong ÷ 4. So every four wrong answers cancel one correct answer. Put differently, each wrong answer costs you 0.25 net.
Examples
- 30 correct, 8 wrong: 30 − 8 ÷ 4 = 28 net.
- 20 correct, 20 wrong: 20 − 5 = 15 net.
- 12 correct, 0 wrong, 8 blank: 12 net. Blanks do not count.
Nets are calculated subject by subject
Net is calculated separately inside each test: Turkish, Social Sciences, Basic Mathematics and Science each give their own net. In the score calculation each test's net is multiplied by its own coefficient, so a high net in one subject does not make up for a shortfall in another at the same rate.
Should you leave it blank or guess?
If you can eliminate two options on a question, guessing among the remaining three has a positive expected net: a 1/3 chance of being right against a 2/3 chance of losing 0.25 comes to about +0.17 net. If you have no idea about any option, leaving it blank is safer. This is not a rule; during the exam the decision depends on what you know and how much risk you are willing to take.
How should you track your net?
- Write down your net for each subject in every practice exam.
- Count wrongs and blanks separately. Many wrongs may point to rushing; many blanks may point to gaps in knowledge.
- You can turn your net into a score with the sınavlab score calculator.
The score and ranking you calculate are estimates. The official result appears only on the ÖSYM result document.
