hello ;i am in clss12 -i have studied maths RDSharma and pradeeps for physics,chemistry so is it sufficient to crack iit

No,these books are not sufficient.You need to refer many more books like mole concept book by bharti publication,Moresion and void(organic chemistry),questions and solutions of last 30 years IITJEE papers,Mathematics book by A.DAS GUPTA(TATA MACG. PUBLICATION) and many more standard books to clear your concepts upto JEE heights.

if you have done all the questions and concepts of these books very well then you have covered most of the syllabus from which questions are asked in IIT entrance exams.in addition to these books do more and more problems of physics ,chemistry and maths for that 26 years papers of iit will be more helpful to select in IIT. rivision is must for cracking any exams.best of luck .

These are sufficient for IITJEE mains but for IITJEE Advanced more problem oriented book will be required to strenghten your problem solving.You can solve books of Arihant and Disha publication for problem solving and concept building.

No. RD Sharma and Pradeep's are design mainly for CBSE board, Question Level of these books doesn't match with IIT Jee level, Hardly any question comes from these books in IIT Jee. So it would be better to refer better book (Like MTG, HCV, TMH, Arihant publication) for IIT Jee preparation.
