Your YKS score isn't calculated directly from your net answers. The process runs through four stages: net → standard score → raw score → placement score. This guide walks through what each stage means, and why you can't fully calculate it yourself.
1. Net: The One Number You Can Calculate Exactly
Everything starts with your net score. On every YKS test, four wrong answers cancel out one correct answer:
For example, if you got 28 correct, 8 wrong, and left 4 blank on TYT Math, your net is 28 − (8 ÷ 4) = 26. Blank answers aren't counted at all. You can work out your net in seconds with a net score calculator.
2. Standard Score: Why the Same Net Doesn't Give the Same Score Every Year
ÖSYM doesn't convert your net directly into a score. First it converts it into a standard score: your net is compared against the average and standard deviation of every candidate who took that exam that year.
The practical effect: if the exam is hard, everyone's net drops, the average drops, and your net of 26 becomes relatively more valuable. If the exam is easy, the opposite happens. That's why "what score does 40 net give?" has no fixed answer — it depends on how hard that year's exam was and how everyone else performed.
3. Raw Score: Weighting the Tests
Standard scores are weighted with different coefficients depending on the score track you're applying under, then summed. In the Quantitative track, math and science carry more weight; in the Verbal track, Turkish and social studies do.
The result of this weighting is called your raw score. It's your score before OBP is added, and every candidate starts from a baseline of 100.
4. Placement Score: The OBP Contribution
In the final stage, your high school performance comes into play. OBP (secondary-school achievement score) is your diploma grade multiplied by 5, giving a value between 250 and 500:
Placement Score = Raw Score + (OBP × 0.12)
| Diploma Grade | OBP | Contribution to Placement |
|---|---|---|
| 50 | 250 | 30.00 |
| 70 | 350 | 42.00 |
| 85 | 425 | 51.00 |
| 100 | 500 | 60.00 |
As the table shows, the gap between the lowest and highest OBP is roughly 30 points. That's meaningful, but it's not what decides the outcome — your net score is.
So Can I Estimate My Score in Advance?
Not precisely, because the standard-score conversion needs that year's full set of results across all candidates. Most online "score calculators" use previous years' coefficients and are really just estimates with a fairly wide margin of error.
The realistic approach is to track your net, not your score. If your net is rising over time, your score is too. Logging your practice-test results and watching a 4-6 test trend line is far more reliable than checking a single test's estimated score.
Frequently Asked Questions
Every candidate starts from a baseline of 100. A candidate who answers nothing correctly has a raw score around 100, before the OBP contribution is added.
There’s no fixed answer. Because scores are converted based on that year’s full candidate average, the same net produces different scores in different years. That’s why tracking your net is more reliable than trying to predict a score.
Since your diploma grade doesn’t change after graduation, your OBP is fixed too. But OBP’s contribution is capped at roughly a 30-point range — raising your net score matters far more.
