Hey friend today I am awaring you about the online shoppe site mainly for the study material. The concept was good to spread education in all parts of our country but it last no longer. The content of book is not good it does not provide any deep knowledge also the price of the stuff available is high. Recently I purchased arihant competition book for je exam preparation but I was totally disappointed after seeing this book the book was not printed in a proper sequence the question were not of topic as mentioned in chapter name and many of the question were same. So friend its my humble request for not purchasing book from online site rather it can be better purchased from market shoppe. Thanks.
