Difficulty Level: GS vs CSAT

• GS Paper 1: We will share if the paper was easy, moderate, or hard. A good mix of standard books and current news is always needed to do well here.

• CSAT: In recent years, CSAT has become much harder. It takes more time to read the paragraphs and solve the math problems. You must practice it regularly and not take it lightly.

Current Affairs + Clear Concepts: How to Win

Just reading the daily news is not enough anymore. You must connect the news to your basic subjects. For example, if there is news about a global climate meeting (International Relations), you need to link it to your basic Environment and Ecology notes. Having clear concepts plus reading daily news is the winning formula.

• Read standard books and basic school books (NCERTs).

• Give special attention to high-scoring subjects like Indian Geography and Environment.
