5. Inside the Exam Hall: Key Tactics
For General Studies (Paper I):

- Second Round: Revisit moderate-difficulty questions where you can eliminate 2 options.
- Final Round: Guess only if you’ve eliminated at least one wrong option
For CSAT (Paper II):
- Start with Reading Comprehension (RC) – Shorter passages yield more marks.
- Skip tough Math questions – Focus on logical reasoning and data interpretation.
- Aim for 66+ marks (33% qualifying criteria)
Pro Tip: If stuck, move on—don’t waste time on a single question
