RD Sharma vs RS Aggarwal 2027 — Which Is Better for Board Exams Class 10 and 12 | Padhaao Blog

In short: For CBSE Board Exams, RS Aggarwal is better for most students — it's closer to NCERT level and board exam pattern. RD Sharma is better for JEE/competitive exam preparation — it has harder problems and more variety. If you're only targeting boards, RS Aggarwal + NCERT is enough. If you're targeting JEE alongside boards, use RD Sharma. Don't use both — pick one and master it.

Frequently Asked Questions

Can I score 95%+ with only RS Aggarwal?

Yes. RS Aggarwal + NCERT + previous years is sufficient for 95%+ in boards. RD Sharma is not necessary for board exams.

Is RD Sharma necessary for JEE?

For JEE Main, RD Sharma is very helpful. For JEE Advanced, you'll need additional books (Cengage, Arihant, coaching material).

Which book has better solutions?

Both have solution books available. RD Sharma solutions are more detailed. RS Aggarwal solutions are more direct.

Should I complete the entire book?

No. Focus on:

All NCERT-aligned questions
