I got very less marks in maths so can I get a entrance in government college

Hello there. Hope you are doing good. I would like to tell you that if you are looking for merit based admission in government college, then your aggregate percentage is considered. Your best 4 subjects are considered while calculating your aggregate. So, if you have scored less in one of the subject, then it will not be a problem since you can exclude that subject while calculating your aggregate. But, if you are looking to get admission in a Bachelors degree which is specialized in Maths, then you won't be able to get admission because it is mandatory to include Maths subject in such situation.

I hope you found this answer helpful. Good luck for your future.
