Hello student ,

As per the rules by the government there is no such rules for any particular subject through which you can get admission in government college . All you have to score is minimum 50 percentile for general category in all the three subject  as it has been not mentioned you have to score any particular marks in any one subject  but you still try to score good marks in all subjects to qualify in neet under graduate entrance exam .

Hope this information will help you !

Good luck !
