How to start with failure

Anand, the philosophy which you are following is absolutely correct. But if you are failing continously, there is huge mistake in your study pattern and exam presentation. Do not worry, stay calm, change the way you normally study, do not refer 2 or 3 books at a time, try to write as many mock tests as possible, evaluate yourself, then you will get an idea on what is going wrong. If possible, try to get certified copies of your answer sheets as well.This will help you alot.

I am using munish bandari and practice manual

Costing and fm padhukas and practice manual

Taxation using practice manual

Accounts padhukas and practice manual

This is sufficient right

First complete PM,s with 100% accuracy then if you have time, go through other author books. Do not revise author books first, only if you have any doubt then refer author book. Those books which you followed are sufficient, but you need to revise your way of study, give it a try. Am sure, you will get good results......Cheers
