How do I get admission into MIT/Imperial/Oxford for an MBBS with a scholarship

I don't know about the last two but 1. MIT is not a medical school ( it does do some medical research and has collaborations with some medical schools) And 2) MBBS is not offered in the USA. Best to finish your education where you are and do well before attempting a scholarship at an outside institution.
