Self study of AMA old syllabus

To be honest.. just do OR in p.m (no need of LPP & pert)..
For costing & remaining O.R,
10 attempts question papers and R.T.P's... and remember one thing costing is all about +-*/
Btw i followed it too nd last time scored 59 and now 62

refer sm and pm alongwith with rtp...and to score good in this, make sure that O.R should be super strong ..so first finish it and then start with costing part with small chapter and then only move to the big chapter ( reason is that if u start those big chapter early then it will consume ur lots of time plus thr may be the chances that afterwards u skip the small one)

Old Sanjay Agarwal Sir videos then try and get hold of his solved book for ama and or...really helpful.

Nishant Jain Thanks bro can you please let me know how many attempts RTP is necessary to be worked out? Did you work out sums from study material or any other reference book?
How to go about with the concept part?

10 attempts rtps and question papers.. and make sure u have basic understanding of all concepts.. if u have your class notes, try to go through it..
i never did anything different than this... never leave any chapter in choice.. learn basics of every chapter.. nd need to go for any reference book.. if u want to solve more sums, go for p.m... but i feel its unnecessary, since we can't review every problem before exams..
