Hey Dhanashri

Massachusetts Institute of Technology does not provide a specific central Financial Aid/Scholarships for students aspiring for Graduate programs (Masters).

To get a financial aid, you need to personally contact the particular Department in which you want to study and ask them for aid. That also depends on the field you want to pursue and your extraordinary performance in the past. To get Scholarships you may seek for Fellowships, might get a part time job to pay the fees or Student's loan

All the best
