NTA publishes the JEE Main Answer Key 2027 in two stages. The provisional key comes out first, expected in early to mid February 2027 for Session 1 and mid to late April 2027 for Session 2. Candidates can challenge any question by paying ₹200 per objection. After the review, NTA releases the final answer key just before results are declared.
- Challenges without supporting justification or evidence are not considered.
- The challenge fee is non-refundable and accepted only through the official challenge link on jeemain.nta.nic.in.
- NTA’s decision on each challenge is final, and candidates are not individually notified of the outcome.

Memory-Based Answer Keys: Should You Trust Them?
Before NTA publishes the official provisional version, several coaching institutes release their own memory-based answer keys within hours of each shift ending. These unofficial versions, prepared from student recall and expert review, help you form an early estimate. However, only the official NTA document determines your actual score, so treat memory-based versions as a rough preview rather than a final reference.
How to Calculate Your Score Using the JEE Main Final Answer Key?
Once the final answer key is out, your raw score can be worked out using this formula:
JEE Main Score = (Correct Answers × 4) − (Incorrect Answers × 1)
- This applies equally to MCQs and numerical value questions; both carry four marks for a correct answer and lose one mark for an incorrect one.
- Only unanswered questions, or those marked for review without selecting an option or entering a value, score zero.
- If NTA drops a question from the final key, every candidate in that shift gets four marks for it, whether they attempted it or not.
- Calculate the score separately for Physics, Chemistry and Mathematics, then add all three together.
Example of Score Calculation
| Response Type | Number of Questions | Marks |
| Correct answers | 50 | 200 (50*4) |
| Incorrect answers | 10 | Minus 10 (10*1) |
| Unattempted | 10 | 0 |
| Total | 70 | 190 (200-190) |
This calculation only estimates your raw score. NTA converts raw scores into percentile using a shift-wise and session-wise normalization process.
JEE Main 2027 Expected Score vs Percentile vs Rank
The table below shows the expected JEE Main Marks vs Percentile trend, along with probable rank ranges. Since scores are normalized across shifts and sessions, the same marks can shift slightly in percentile depending on paper difficulty. Use this as a rough guide to estimate your rank before results are out.
| Raw Score (out of 300) | Expected Percentile | Expected Rank Range |
| 280–300 | 99.95 – 100 | 1 – 500 |
| 250–279 | 99.8 – 99.94 | 500 – 3,000 |
| 220–249 | 99.5 – 99.79 | 3,000 – 8,000 |
| 200–219 | 99 – 99.49 | 8,000 – 15,000 |
| 180–199 | 98 – 98.9 | 15,000 – 25,000 |
| 150–179 | 95 – 97.9 | 25,000 – 45,000 |
| 120–149 | 90 – 94.9 | 45,000 – 75,000 |
| 100–119 | 85 – 89.9 | 75,000 – 1,10,000 |
| 80–99 | 75 – 84.9 | 1.1 – 1.8 lakh |
| Below 80 | Below 75 | 1.8 lakh+ |
