JEE Main Marks Calculator
Students checking mocks, response sheets, or answer-key performance.
It gives a quick, calm scorecard after a mock or official answer-key check.
If Physics is 18 correct, 4 wrong, 3 skipped, score = 18 x 4 - 4 = 68.

Logic
Formula and validation
Formula / logic
Subject score = correct x positive marks - wrong x negative marks. Total score = Physics + Chemistry + Maths. Accuracy = correct / attempted x 100.
Validation rules
- Numbers only
- No negative values
- Correct + wrong + unattempted should equal total questions for each subject
- Total cannot exceed selected pattern

Trust note
Use official portals for final decisions
Raw marks, percentile, and rank decisions are final only when released by NTA.
College and cutoff tools are planning aids. Seat allotment depends on official JoSAA/CSAB rules and rounds.
Prediction calculators show ranges because exact future outcomes cannot be known from static inputs.
FAQs
Student questions
How is JEE Main score calculated?
Correct answers get positive marks, wrong answers lose marks, and unattempted questions get zero.
Does a wrong answer reduce marks?
Yes, the default JEE Main Paper 1 setting uses -1 for a wrong answer.
Can I calculate subject-wise score?
Yes. Physics, Chemistry, and Maths are calculated separately and then added.
Can I use this for mock tests?
Yes. Use the custom pattern option if your mock has a different question count.
What if I leave a question unattempted?
It adds zero marks and is counted as skipped.
Is this calculator official?
No. It follows standard marking logic but is not an official NTA tool.
Can I paste answer key?
Yes. Paste C, W, and U style tokens to auto-count correct, wrong, and unattempted answers.
Does the calculator work for both sessions?
Yes, raw score calculation works the same when the marking scheme is the same.
What happens if a question is dropped?
Use the note field and adjust total questions or correct count according to the official key instruction.
Why is accuracy shown separately?
Accuracy helps you see whether score loss came from low attempts or too many wrong answers.
