Formula
marks = 4 × correct − 1 × wrongmaximum = 180 questions × 4 = 720
- 45 questions each in Physics, Chemistry, Botany and Zoology
- Unattempted questions score 0
Four marks for a right answer, one mark off for a wrong answer, nothing for a question you skip.

How it works
NEET (UG) has 180 questions in a single sitting: 45 each in Physics, Chemistry, Botany and Zoology, with every question compulsory. A correct answer earns 4 marks, a wrong answer costs 1 mark, and an unattempted question scores nothing, so the maximum is 720. Every source checked for recent years agrees on this scheme.
Enter your correct and wrong answers for each subject, ideally from the official answer key, and the calculator totals the marks, shows the marks lost to wrong answers and gives your accuracy. If you also know the official qualifying marks for your category in your year, add them to see how far above or below you are.
A raw score is not a rank and not a qualifying status: the NTA declares qualifying marks each year based on a percentile rule, which the NEET Qualifying Cut-off Checker applies. To see the score as a plain percentage use Marks Percentage Calculator, or try a different scheme with the generic Exam Score Calculator.
