MBBS

Hello,
To pursue MBBS from USA, you must first complete your Bachelor's degree preferably from USA, clear the Medical College Admission Test which is MCAT and seek admission into a medical school. There is no MBBS degree as such and the process mentioned above is the typical procedure to study medicine in USA. Take your SAT and TOEFL to apply to Bachelor degree programs. You must also be academically very bright.

MBBS is far better than B.Sc in nursing. It has a good scope and market demand as well.

Your profile is exceptional for being a prospective IIM-A PGP student. I would suggest that you should study hard and try to score more than 95-97 percentile in CAT to get a call from IIM-A.

470 marks is a good score. It is good enough to get State Quota Colleges and Private ones of MBBS.

There are many occupations that may directly or indirectly involved Medical Science which you'll be at par with already high paid professionals. Mainly Sports Field and Industry is so which is quite in demand all over the globe. And yes country matter is clearly depending on your ability to work.

MBBS is a professional course especially where the profession involves working hard to pay the price of saving a life so distance course is a myth.

Yes, provided that you satisfy eligibility criteria like required minimum score and educational qualifications.
