Books for ipcc-group-i

For Accountancy PC Tulsian's book is the best for self preparation.

In my opinion, TN Manoharans book is the best for Income Tax. It only contains what is necessary and that too in very easily understandable language.

For all other subjects, the study materials issued by the institute is enough

If you really want to gain a maximum knowledge go for

P C TULSIAN-Accounts

LAW-MUNISH BHANDARI

ETHICS AND COMMUNICATIONS-PRACTICE MANUAL

TAXATION-V K SINGHANIA

Just Passing the exams is not important,Passing the exams with great conceptual clarity is Important!!
