How it works
Using the Challenge Evaluation Predictor in three steps
Every step below reflects the actual calculation this tool runs, so you can check the result by hand if you need to.
- 1
Enter the marks awarded in the paper you want to challenge and the marks you expect after re-evaluation.
- 2
The tool recomputes the subject total, the pass status and the effect on your SGPA.
- 3
You can then judge whether the likely gain justifies the challenge evaluation fee and waiting period.
About this tool
Challenge evaluation gets your answer script re-examined, but it carries a fee and can move the result in either direction. The predictor compares your expected marks with the awarded marks and highlights how large the gap needs to be before an application is likely to be worthwhile.

AKTU requires passing both external end-semester theory exams and overall subject aggregate. Internal sessional marks are combined with external marks.
| Assessment Component | Max Marks | Pass Marks | Official Guidelines |
|---|---|---|---|
| External End-Sem Theory | 70 Marks | 21 Marks (30%) | Mandatory minimum in end-semester theory exam. |
| Internal Sessional Assessment | 30 Marks | No individual cutoff | Internal marks combine with external to reach 40% aggregate. |

| Practical / Lab / Viva | 50 / 100 Marks | 50% | Minimum 50% required in practical & viva examinations. |
Grace Marks Policy
AKTU awards up to 7 to 10 grace marks per academic session for borderline failed subjects to help students reach the 40% aggregate threshold (awards Grade E). Grace marks block Honours degree eligibility.
ATKT & Carry-Over Progression Guidelines
- Students can carry forward failed subjects (Carry Over Papers) to subsequent semesters.
- Clearance of carry-over subjects replaces zero grade points with earned points.
- Honours division requires clearing all subjects in the first attempt without carry-over or grace marks.
