How it works
Answer Key Marks Calculator
After every competitive exam, the first thing students want to know is their expected score. But manually calculating marks with negative marking is tedious and error-prone — especially when different sections have different marking schemes (JEE Main has +4/-1, NEET has +4/-1, CAT has +3/-1).
This calculator handles all major exam marking schemes. Select your exam preset (JEE, NEET, CAT, GATE, UPSC, SAT, ACT, GRE) or enter custom positive and negative marks. Input the number of correct, wrong, and unattempted questions to instantly get your total score, accuracy percentage, and marks lost to negative marking.
The visual breakdown shows how much each section contributed to your score and how many marks went to negative marking. Switch between exam presets to compare scoring patterns. All calculations run locally in your browser.
