Hi aishu,
No from what I have heard he is a scamer. I am not sure if it is a book or not. All my friends were advised to stay away. He is not even a DDS, DMD, nor MD. For example here is another one of his pages for the medical students
http://www.mo-media.com/usmle/
The testimonies are the same on both pages. He has them form mcat and many orhte corses. Its a scam so do not waste your money nor time.
Hope this helps
