Hii,

I am sorry to inform you but you can't get admitted into IIT just after JEE Mains. After clearing JEE mains you are supposed to give JEE advanced also and after clearing that exam you'll be called for counselling and on the basis of your rank and preference of your college you'll be allotted with a college.

Hope this helps.

All the best!!
