Xam idea is like a burden because in Xam idea books if we especially talk about science then it is not good for the exam as well as for knowledge also.Xam idea contains too much question which are not good for exam point of view. The solution which was provided by the Xam idea is also very tough and also in hard language.It also not provides topper answer which is also not a good thing.
The notes which were provided by the Xam idea is also very short. It provides notes of the whole chapter in a single page. The sample papers of this book is not so as compared to Oswal sample papers book.
So, I do not recommend anyone to buy the Xam idea book, you may buy Oswal, Evergreen or any other Publication who provide the answer in simple and easy language.
