Help me for adv!

First, I am a dropper, and my mains 1 went very well, expecting 240-250 marks. I am hoping to advance for under 400 rank.

So for the mains, I have done these things (theory):

MATHS : I have solved the Cengage Adv book set only.

Chemistry:-

OG- I have completed the lecture of Neeraj Saini (NS) sir from yt and no special practice(only from pyqs and mocks)

PC & IOC - From ALK sir and same no special practice.

PHYSICS:- I have done theory from ABJ sir.

So for advance, I think I am ready with theory, just need practice of questions.

So suggest me books (especially for Chem) / course for question-solving!

I am going to attempt 2021-2025(Jan) mains pys + Mathongo test for the mains April attempt.

For adv maths I am thinking of solving DPPS came with Cengage for practical and for advanced phys thinking of buying a PG 700+ ill book.

Also suggest me test series for advance
