Hi Raghav,

Hope you are okay.

Allen modules are sufficient and choosing them for preparation is a good move.These modules really help especially in Organic chemistry. You get a decent JEE Rank if you are comfortable solving these questions. Though there are too many exercises it really helps for both JEE Mains and advanced.

Make sure you all check through the previous year papers of last 5-10 years. This helps you to understand the difficulty level of questions set in the question paper.

Hope this helps..

All the best..
