Frequently Asked Questions

Q.Are Prelims marks included in the final ESE merit list?

Yes. This is a key difference from CSE. ESE Prelims marks (500) are included in the final merit along with Mains (600) and Interview (200). Candidates should not treat Prelims as merely qualifying.

Q.Is there negative marking in ESE Prelims?

Yes. There is a deduction of 1/3 mark for each wrong answer in both Paper-I and Paper-II of ESE Prelims. Avoid random guessing.

Q.What is the difficulty level of ESE Mains conventional papers?

ESE Mains conventional papers are significantly harder than GATE. They require multi-step design calculations, derivations, and application-based problem solving – not just conceptual understanding.

Q.How are candidates shortlisted from Prelims to Mains in ESE?

UPSC shortlists approximately 6–7 times the number of vacancies per branch from Prelims to Mains, based on Prelims merit within each engineering branch.
