Exam

It depends on the results of JEE Advanced. In order to get admission in IISC, you must score AIR rank under 50 and in IITs. It must be under 5000.

According to me, the cut-off for JEE Mains will be around 95-105 and this will be the score that will be required to qualify for JEE Advance and the result for Mains is going to released by tomorrow. By then, all will be cleared.

I will prefer you to attend the counselling, because some seats are always left vacant. You might be lucky that you will get the CS branch, otherwise the possibility is very low, because CS branch gets full very soon.

Exams like SAT MCAT, ISAT, GMAT TOEFL may be required depending upon what University you wish to get into.

DU will conduct entrance test for 9 of its UG courses. BMS, BFIA, B.A. In PE & HE&S, B.A. Business economics, B. El. Ed. , B.Tech, B.A. Hons (humanities and social sciences, multimedia and mass communication), B.A. Music.
