Class 12-science

I think UG in biotechnology would be the best option for you.

Not so difficult for you because you have passed class 12th exam with physics which is a counting subject and it proves that your maths is strong to pursue B.Com.

Yes, NIOS students are eligible for MBBS.

Hi Pawan,
Which course you should pursue must be decided by you, based on your career aspirations and interest. You may study medical if you desire. Alternatively, you may look for other options like B.Sc Agriculture, B.Sc in Biology or Chemistry or Zoology, B.Sc in Forensic Sciences, B.Sc Environmental Science, B.Sc Food and Nutrition and many more. You can select the universities after you have decided what to study. Here is a comprehensive list of all options available:

Hi Basavaraj,

NCERT books are the best ones for Physics, Chemistry, and Maths. They have all the topics covered which are asked in boards questions paper.
After completing the unsolved and exemplary questions, go for the previous year papers and few sample papers (Arihant preferably).

Russia and phillipines are good options.but those degree dont have any value in india because in russia,every 2nd person is doctor.so u might think how easy to do MBBS from there.

There is no upper limit, but minimum percentage is 60 %, if you score 60%, then go ahead. Best of luck.
