CBSE 12th

Of course. It doesn't matters that one has passed through main exams or compartment of intermediate boards. What matters is that one has passed or not.
Even passing through compartment, one should never lose the hope of catching his/her dreams.
Of course you can apply for exams if your overall percentage is above the required percentage.

First, you need to pass class 12th with 85 percent marks, then give IELTS exam and score 8.5 marks in it, then give MCAT exam and if you get clear make a passport, then visa of USA and most important keep Rs. 1 core for your 5 year MBBS.

You should go for Nepal, Bangladesh, Ukraine and Philippines. I would suggest you do the seat booking as soon as possible, so that the college will provide huge fee discounts during the admissions.

Hi,
With your graduation score you will not be able to get admission in full time MBA. I think you can try for distance MBA.
