Frequently Asked Questions

Q.Are standard engineering university textbooks enough for ESE?

Yes, standard textbooks form the core. However, supplement them with UPSC ESE PYQ papers to understand which types of problems UPSC asks, especially for the conventional Mains papers.

Q.Is B.S. Grewal enough for Engineering Mathematics in ESE Paper-I?

B.S. Grewal covers the syllabus well. Supplement it with ESE Paper-I PYQs to practice the exact question types asked by UPSC. Focus on Linear Algebra, Differential Equations, and Probability.

Q.How much time should be spent on Paper-I (GS) vs Paper-II (Technical) in ESE?

Most successful candidates spend 25–30% of preparation time on Paper-I and 70–75% on technical subjects. Paper-I carries 200 marks vs Paper-II's 300 marks in Prelims – both are important since marks count.

Q.Are there dedicated books for ESE conventional Mains papers?

Yes. Look for publisher-compiled ESE Mains Conventional Question Banks that compile branch-specific solved previous year papers. Practicing from these alongside standard textbooks is the most effective approach for Mains preparation.
