Harvard University

Hi Aditya,
Harvard being one of the best business schools in the world enormous hard work will be required to get admitted. Academically, you must be a brilliant student and if not, there must be something in your profile which can distinguish you from other students. Besides academics, you must be involved in extra-curricular too. Overall, a strong and all-rounder profile is required. Most importantly you must have work experience before applying so after you complete your Bachelors get a job, take your GMAT and TOEFL. Career planning is also important. Read HBS MBA website for details.

Hi Rahul,
There is no set criteria but your entire academic record from 10th onwards is very crucial. Both your academic performance and extra curricular activities will play an important role during the admission process in these top ranked and selective universities. 70% or more and SAT score of 1350+ is suggested.

Probability of getting admission in MIT or Harvard based on your current and fore casted performance is low.
