Based on initial student feedback and expert evaluation, the overall paper was moderately difficult with conceptual and application-based questions.
| Subject | Difficulty Level | Key Highlights |
|---|---|---|
| Physics | Moderate-Hard | Numerical-based & conceptual application questions |
| Chemistry | Moderate | Balanced mix of theory & reaction-based problems |
| Biology | Easy-Moderate | Mostly NCERT-based & scoring |
| Mathematics | Hard | Logical reasoning & lengthy calculations |
| Parameter | Rating |
|---|---|
| Paper Difficulty | Moderate-Hard |
| Cut-off Expectation | Higher than last year |
| Scoring Trend | More conceptual and analytical |
Here’s a look at the Minimum Admissible Score (MAS) and Merit Index (MI) from earlier years. These give you an idea of what kind of score range usually qualifies for the next round.
|
Year |
MAS |
MI |
|
2024-25 |
76 |
122 |
|
2019-20 |
99 |
159 |
|
2016-17 |
94 |
150 |
|
2015 |
109 |
175 |
Scores vary each year depending on the paper’s difficulty. But as a rule of thumb, if your estimated score is above the MAS, you’ve done well.
Although the official cutoff will be released later by IAPT, based on student feedback and expert analysis, the cut-off for NSEJS 2025-26 is expected as follows:
| Category | Expected Cut-off (Out of 180) |
|---|---|
| General | 75 – 85 |
| OBC | 72 – 80 |
| SC/ST | 60 – 70 |
Cutoff may vary depending on difficulty level, number of candidates, and performance statistics.
Students who qualify NSEJS will be eligible to participate in the Indian National Junior Science Olympiad (INJSO). Final selections eventually lead to training camps and representation of India in IJSO.
| Stage | Exam/Event |
|---|---|
| Stage 1 | NSEJS |
| Stage 2 | INJSO |
| Stage 3 | Orientation-cum-Selection Camp |
| Stage 4 | International Junior Science Olympiad (IJSO) |
The official NSEJS answer key 2025-26 is expected to be released soon on the IAPT official website. Candidates can check the status regularly and compare answers with Aakash’s expert key.
To calculate expected marks, follow the marking scheme:
