Harvard University

You will have to give standardized test like SAT or TOEFL but you have less marks in 12th. Wish you luck.

I think they are providing only post graduation in business management. You should check the website of the University for different courses and their eligibility criteria for future preparation.

Hi, a good SAT for these top colleges is around 1450 and above.You should also visit their websites to know about the average score requirements.

Hi,
Keeping aside your academic grades if your overall profile is not impressive then I am afraid chances are poor. Extra curricular activities which can be in the form of voluntary work, project work, sports, etc., are a must. Also, why do you want to take both SAT and GMAT? SAT is for admissions into UG programs while GMAT for MBA. You should decide what to study first, check the admission requirements on university websites and have a fair idea of what is required and what is not.
Good luck.

Yes, if you are capable enough and scored good grades in B.Tech then you will surely get admission there.

Hi,
It is not necessary but having a degree from a reputed university will keep you in high standing and may increase your chances only if you have a good profile.

Work experience is not mandatory for admission in majority of international B-Schools for MBA but all these BSchools prefers students with work experience.

Hi Rohan,
Your marks are exceptionally good. But to get admission in Stanford or Harvard you just not need to be perfect in academics but in extra circular activities too because they don't need a studious dumb student. In fact, they want an around. Try to maintain your marks above 85 or 90% in your every semester (it has weightage). After your GRE score followed by IELTS bands (mini 7 band needed). At least 2 or 3 year of work experience and Essays writing along with your attractive CV. The procedure is quite long.
