Estimate. MEB converts nets to standard scores using each test's mean and standard deviation for that year, weights them (Turkish, mathematics and science count four times, the others once) and rescales to 100 to 500. The statistics here are typical of recent years. Net = correct minus a third of wrong. Parameter set: 2026
How the LGS central exam is scored
The LGS central exam used for admission to selective high schools has six tests: Turkish, mathematics and science with 20 questions each, and history of revolution, religious culture and English with 10 each. Three wrong answers cancel one correct answer. MEB converts each test's net into a standard score, multiplies Turkish, mathematics and science by four and the other three by one, adds them up and rescales the weighted total so that the lowest candidate gets 100 and the highest 500. Placement then depends on this score and the percentile rank it implies.
Steps
- 1 Enter correct and wrong answers for each test from a practice exam; nets appear immediately.
- 2 Read the estimated central exam score on the 100 to 500 scale and the weighted standard score behind it.
- 3 Change one test to see its effect: a net in mathematics or science moves the score far more than a net in religious culture or English.
Why some tests weigh more
Turkish, mathematics and science carry a weight of four, the three ten-question tests a weight of one. Combined with the standard-score conversion, a single mathematics net is typically worth several times a single English net. Mathematics also has the lowest average, so each net there lifts the standard score the most.
Percentile and placement
Schools are chosen by percentile rank rather than raw score: the most selective science and Anatolian high schools fill from roughly the top one percent, which in recent years corresponded to central exam scores around 480 and above. Full nets in every test give 500. Published cut-offs from the previous year are the practical reference for a target.
Guessing under the one-third rule
Because three wrong answers cost one correct, a random guess among four options is roughly neutral and a guess after eliminating one option is positive. Leaving a question blank costs nothing. Practice tests scored with this tool show whether your guessing strategy is helping.
Limits of this estimate
The means and standard deviations are typical recent values, not those of your exam year, and MEB anchors the scale to the actual lowest and highest candidates rather than to zero and full nets. Expect the official score to differ by some points. The official MEB result is the only authoritative score.
