If you are not strong in mathematics, then don't think about physics because physics always use calculation.

Yes my dear, you can do M.Sc if you've got more than 45% to get admission in a good University.

Hi,
Well, it is not compulsory to take mathematics in class 11th because for medicine, it is not required but you have to study 2 topics of mathematics, i.e. derivatives and integration for your physics subject. According to me, you should not drop mathematics because if you didn't get admission in any medical field, then you can't go for engineering or related to that field. So, take mathematics subject, if only you have 100% confidence among yourself that you can take admission in medical field.
Good luck.

You are eligible to apply for M.Tech if you have done M.Sc IT from a recognized university or institute.
