Hello Aspirant
.
But diploma students are not eligible for jEE mains and advance. Anyway I will provide information about how to crack IITs.
Firstly you should be qualified in jEE mains exam then only you are eligible for jEE advance.
These books are enough to crack jEE advance exam to get into IITs:

• for physics H C Verma
• For chemistry O P Tandon
• For mathematics R D sharma, Arihant

If you want more information once go through the below link:
