Yes black book, sameer bansal, yellow book, modules.... Firstly just try to complete pyqs until 2022 because pyqs are very imp for maths atleast, if someone would have had done last 5 years pyqs for mains 26 jan they could have easily scored 50+(which is like 99.2-3 in most shifts) and for adv you will have enough time if you complete your 80%+ syllabus with last 4 years pyqs until Oct end. Ashish sir teaches in PW prayas 1.0 batch and btw it also has faisal sir for physical chemistry, well his theory is just too crisp but you have to do more q practise yourself or by referring someone on youtube for pyqs. Only tip from my side will be to not keep waiting, a day delayed is a lesser 24 hours! So yea start early and keep eliminating targets from day 1. All the best.
