Life Science

Yes, you can, provided the specific college or university you are applying allow you to.
Having said that I personally think it is better to remain committed to one field. Later, when you will be looking for jobs, that might be concerned as recruiters like people who specialize. But then again, do whatever you feel okay in doing and whatever happens, do not regret your decision ever. Good Luck.

It is advised you to check the same with college, as they have not mentioned the same online.

Kindly check the same with the college itself, as they do not disclose the syllabus online.

I don't think Presidency offers biological science but you need to confirm that from the administration office. As far as I know, Presidency offers B.Tech, BBA LLB, B.Com LLB and MBA.

I don't think you can apply to any university if you don't complete your 12th. Please clear your backlog and try again? Still, for the complete confirmation, contact the admissions office.
