I feel strange that you are asking this thing when the exams are on your head. Anyway, to start with you can simply use Shukla and Grewal - Volume 1 & 2. for your self study. For AS/IFRS - Use Bharat Publication's book or you can also use Taxmann's books.
One suggestion - since you have only 2 months left, don't try to solve the exercise questions. Focus only on the solved examples and illustrations. and see the answer where ever you are stuck. It will boost your confidence.
