Hello,
Admission to all the 23 IITs be it IIT Bombay or IIT Delhi is done on the basis of rank secured in JEE Advance. To appear for JEE Advance a candidate need to qualify JEE Main. After you qualify JEE Mains and secure a good rank in JEE Advance you can select your preferred branch in IIT Bombay during JoSAA Counselling. Also you need to fulfill the basic minimum eligibility criteria for both JEE Mains and Advance.
