Frequently Asked Questions

1.What does the year-wise question count (e.g., "2026: 9 Qs | 2025: 15 Qs") mean?

It shows how many questions were asked from that chapter in each year's papers, so you can quickly spot chapters with consistently high weightage as well as ones where the number of questions has changed over time.

2.Are chapters the same across Biology, Chemistry, Mathematics, and Physics?

No, each subject has its own distinct set of chapters, listed under its own heading. Use the Biology, Chemistry, Mathematics, and Physics tabs at the top to jump to a subject.

3.Can I see chapter-wise trends going further back than 2025–26?

Yes, the PYQs span 2011 to 2026; the year-wise numbers shown alongside each chapter reflect the two most recent years, while the full historical range is available once you open the chapter.
