Dear Rohit

For A/Cs & Cost +Fm refer your Class notes.
For Law :Munish bhandari
For Ethics & Communication:Practice manual or Module of ICAI
For Audit:Only Surbhi Bansal Mam
For Income Tax: V K Singhania is Good but too much lengthy n bad to read because of presentation like small fonts, referring page no. etc. for exam point of view Girish Ahuja is Best.
For Info Tech use Dinesh Madan
For SM refer institute module... it is the best
