A JEE Main marks calculator works out your raw score as 4 times your correct answers minus your wrong answers, so 55 correct and 13 wrong gives 220 minus 13, which is 207 out of 300. This rule now applies to both the MCQ section and the numerical section of every subject.
Paper 1 (B.E. and B.Tech) has 75 questions: Physics, Chemistry and Mathematics with 25 each. Pull your answers from the response sheet, match each with the key NTA publishes, and enter right and wrong totals in the calculator above. NTA has the last word on both score and percentile.

Raw score = (4 x correct) - (1 x wrong)
Correct and wrong are totals across all three subjects and both sections. Unanswered questions add nothing and cost nothing. The maximum is 75 x 4 = 300.
How to use the JEE Main marks calculator above
The calculator asks for two numbers per subject: questions you got right and questions you got wrong. Anything not entered is taken as unanswered. Physics, Chemistry and Mathematics are scored separately so you can see which subject pulled your total down.
- Correct: your chosen option ID (or integer) matches the key.
- Wrong: you saved an answer and it does not match.
- Not answered: left blank or only marked for review.
The result panel shows each subject out of 100, the total out of 300 and your marks as a percentage. A subject has only 25 questions, so right plus wrong can never be more than 25; if your entry crosses that, recount.
- Log in to the JEE Main portal and open your response sheet and the answer key.
- For each subject, mark every question as correct, wrong or not answered.
- Do this for Section A (20 MCQ) and Section B (5 numerical) separately.
- Enter the correct and wrong counts per subject in the calculator.
- Read the subject scores and the total out of 300.
- Repeat with the final answer key when NTA releases it.
The current JEE Main marking scheme, section by section
Each subject has two sections. The old rule where you picked 5 numericals out of 10 has gone, and so has the zero penalty on numerical answers. Many older pages and videos still say otherwise, so trust the latest information bulletin.
| Part | Questions | Right | Wrong | Max marks |
|---|---|---|---|---|
| Section A (MCQ), each subject | 20 | +4 | -1 | 80 |
| Section B (numerical, integer answer), each subject | 5 | +4 | -1 | 20 |
| One subject | 25 | 100 | ||
| Whole paper (Physics, Chemistry, Maths) | 75 | 300 |
Numerical answers are integers. NTA rounds the answer to the nearest integer, so the key gives a whole number and you match it against what you typed.
Worked example: scoring a full response sheet
Physics: MCQ 18 right, 2 wrong. Numerical 3 right, 1 wrong, 1 blank. Right = 21, wrong = 3. Score = 84 - 3 = 81.
Chemistry: 20 right, 4 wrong, 1 blank. Score = 80 - 4 = 76.
Mathematics: 14 right, 6 wrong, 5 blank. Score = 56 - 6 = 50.
Total: 81 + 76 + 50 = 207 out of 300. Check: 55 right x 4 = 220, minus 13 wrong = 207. As a percentage of marks, 207 / 300 x 100 = 69 percent.
The check line matters. Adding subject totals and then recomputing from overall counts catches most typing slips.
What a wrong numerical answer now costs
Because Section B carries the same minus 1 as Section A, a guessed integer is no longer free. Suppose you fill all 5 numericals in Mathematics with guesses and only 1 is right. You get 4 for that one and lose 4 for the other four, so the section gives you 0. Leave all five blank and you also get 0, with no risk of going below it.
Four wrong answers cancel exactly one right answer in either section. So 10 right and 8 wrong in a subject gives 40 - 8 = 32, while 10 right and none wrong gives 40.
Quick table of raw scores
Find the row nearest to your own counts. Every row adds up to 75 questions.
| Correct | Wrong | Left blank | Raw score out of 300 |
|---|---|---|---|
| 75 | 0 | 0 | 300 - 0 = 300 |
| 70 | 5 | 0 | 280 - 5 = 275 |
| 65 | 8 | 2 | 260 - 8 = 252 |
| 60 | 10 | 5 | 240 - 10 = 230 |
| 55 | 12 | 8 | 220 - 12 = 208 |
| 50 | 10 | 15 | 200 - 10 = 190 |
| 45 | 15 | 15 | 180 - 15 = 165 |
| 40 | 12 | 23 | 160 - 12 = 148 |
| 35 | 15 | 25 | 140 - 15 = 125 |
| 30 | 10 | 35 | 120 - 10 = 110 |
| 25 | 12 | 38 | 100 - 12 = 88 |
| 20 | 10 | 45 | 80 - 10 = 70 |
| 15 | 8 | 52 | 60 - 8 = 52 |
Where to find each number on the response sheet
Your response sheet on the JEE Main portal lists every question by a question ID, its status (answered, not answered, marked for review) and the option ID or integer you saved. The answer key lists the same question IDs with the correct option ID. Match them one by one.
- Count a question as correct only if the IDs match exactly.
- If NTA drops a question in the final key, check the final key notice to see what credit it carries before you count it.
- Session 1 and session 2 have different papers and keys, so score each attempt against its own key.
For a JEE Mains session 2 marks calculator, use the same tool: the marking does not change between sessions. NTA keeps the better of your two NTA scores for the merit list.
Common mistakes when you calculate JEE marks
| Slip | What goes wrong | Fix |
|---|---|---|
| Giving numerical answers zero penalty | Under the current pattern a wrong integer answer loses 1 mark, the same as a wrong MCQ | Count numerical errors in the wrong column |
| Counting only 5 of 10 numericals | The internal choice was removed; there are exactly 5 numericals per subject and all count | Enter all 5 per subject |
| Checking against the provisional key only | Some answers change after challenges | Recheck once the final answer key is out |
| Treating raw marks as percentile | Percentile compares you with your shift, it is not marks out of 100 | Use the percentile page for that step |
| Adding marked for review as correct | A question left unanswered or only marked for review scores 0 | Count only answers the response sheet shows as answered |
| Mixing up option IDs | The response sheet shows long option ID numbers, not A, B, C, D | Match the ID in the key to the ID you chose, line by line |
From marks to percentile and rank
Raw marks get you halfway. NTA turns them into a percentile within your shift: 100 times the number of candidates in that shift who scored the same as you or lower, divided by everyone who appeared in that shift. The same 207 can give a different percentile in an easy shift and a hard one, so no fixed marks to percentile table exists. Use the JEE Main percentile calculator for that estimate.
If you are also writing JEE Advanced, that paper uses partial marking and a scheme that changes every time. State engineering exams such as MHT CET and EAMCET have their own rules. For any other paper, the response sheet marks calculator lets you set the marks yourself.
Questions students ask
How do I fill the JEE Mains marks calculator from response sheet details?
Open your response sheet and the answer key, mark each question right, wrong or blank, and type the counts per subject into the calculator. It applies +4 and minus 1 and shows your total out of 300.
Is there negative marking for numerical questions in JEE Main?
Yes. Under the current pattern a wrong numerical answer loses 1 mark, just like a wrong MCQ. A blank numerical answer gets 0.
Will my JEE Mains marks calculator from answer key result change later?
Yes. Score yourself with the provisional key first, then repeat with the final key. Your score can move if NTA changes or drops answers after challenges.
Does the JEE marks calculator work for session 2?
Yes. Both sessions follow the same 75 question, 300 mark pattern with the same marking. Just use the key for the session and shift you wrote.
Is there a JEE Mains marks calculator bot I can trust with my login?
You do not need to share your login with any bot. Read the counts from your own response sheet and type them here. Your password stays with you and the counts are all the tool needs.
Is 207 marks the same as 69 percentile?
No. 207 out of 300 is 69 percent of the marks. Percentile is a different number that depends on how others in your shift scored.
What is the lowest possible score in JEE Main?
If you attempt all 75 questions and every answer is wrong, you get minus 75. A blank paper scores 0.
