I am a below average student can't understand things easily and i have chosen not to go for tutions for pcc, but some of my friends say some concepts cant be cleared without tutions, so can some one tell me which one of these books should be chosen for self study for accounts in pcc in punjab which can clear all my concepts without leaving doubts, please tell me if there is any other book also better than those mentioned below:
