USA

Most universities offer MS courses which are completed within 2 years. However, I have shared a link with you, and you can check on your own if there are any MS courses which are of 3 years duration. You may be able to get an extension for your MS course up to 3 years in select universities.

Hi Aman,
65% is a mediocre score for universities like MIT. To get admission there or any top ranked university, you must have a very good profile, an all rounded profile. If you have anything unique in your profile like sports or other extra curricular activities which you excel in apart from your studies only then you have a chance. You will also need a good SAT score. Please go through MIT website and read about the selection process and students they admit and prepare accordingly.
