Hello Dear,

As you know they look for everything like your previous academics. MIT reviews your application holistically, before arriving at a admission decision. They have extreme interview session too.

1. Some basic portion or percentage of your 10th,12th marks, but that has very  little importance
2. Your Examination score such as TOEFL, GRE, etc
3. Interview
4. Journals, Publication, papers produced.

Good Luck
