Hi Nisha,

Indian Institute of Technology (IITs) are the pioneering education institutions of India which offers a number of courses at undergraduate, post-graduate and doctoral level. You haven't mentioned which course would you like to get admission. Nevertheless, if you would like to get admission in undergraduate engineering courses then you will have to crack JEE Advanced after clearing JEE Main. JEE Advanced is conducted every year by top seven IITs on rotational basis. Once you clear the entrance examination you will be admitted to these reputed institution via JoSAA counselling.

Hope it helps you.
