Carefully read the explanations that apply the elimination technique. Try to replicate the method without looking at the answer first. Over time, this will develop your logical guessing and risk management in the exam hall.

Use the 5-year trend analysis to identify which topics have been frequently asked. Focus your revision and test practice on these high-yield topics.

Many aspirants make the mistake of ignoring Paper 2. The CSAT section of this book includes real previous year questions with detailed solutions, helping you identify your weak points early on.

6. Use the Mains Section for Value Addition

Use the Mains-focused questions and essays to understand what kind of depth is expected in the second stage of the exam. The overlap in GS topics between Prelims and Mains makes this a smart way to prepare both together.

7. Revise with the 3500+ Bullets

Keep the revision bullets for the final 15–20 days before the exam. These help you go over vast topics quickly without opening multiple books.
