Is it right book?

Girish ahuja is the top most directtax expert in india,who hosted more than 2000 seminars on directtaxes

and he is one of the person out of four people appointed by icai to comment on Direct tax code.

However,i will prefer T N manoharan,book for ipcc nov.2012

No doubt Girish Ahuja sir is a great renowned personality in the field of taxation and his books are very popular among professionals and tax practitioners but dont know how is his book for ipcc level. I also recommend TN Manoharan Sir's book. I found it very nice for self study. But you may go to a book shop and compare both books n select what you feel is better for you. Good Luck.

Go for t n manoharan or t g suresh. Girish ahuja is not good as compare to above.
