Is M.L.KHANNA GOOD book for maths for iit.Are all the topics well explained there... If not please suggest me a better book

ML khanna is of course a good book and all the syllabus is fully covered . If you are studying it properly there is no need to even think of other book .

Please make it a point to study a book more number of times than to study a more number of books. All the books are more or less the same . So

stick to your current book and best of luck with your preparation.

book is good but not enough use amit m agrawal
