Hey Yatharth ,
There are many colleges in India , providing BCA and MCA courses to students from non mathematical background . As per your concern on faculty and infrastructure I will provide you list of top colleges where you can persue this course .

The universities which give admission to non mathematical or computer based students may have entrance exam or minimum cut off percentage . Some colleges or universities consider a minimum aggregate of 45% -60% at 12th level with English . The stream however doesn't matter .
Other open distant learning universities like PTU , IGNOU offer BCA and MCA course without maths being a mandatory subject .
In case you face some problem , then you can appear for NIOS on - demand maths exam (12th) . There are other various universities that will accept your score in the above mentioned basis .

Just the crises lies in the way you Persue your studies . Being a student of biology , you will probably have less knowledge on computer and maths or technical approach as compared to the one who will remain go easy during the first month of the course . Yet not to worry if you be in touch to your studies on a regular basis . As you lack basic concepts this will create some problem during the start , but you can cope up with efforts . The maths that you study in 12grade gets its higher version in BCA , this would also create preliminary problems . So it is going to be tough at first but regular work and efforts will probably make you have fun in the field . If you have interest in field of technology and computers it won't be a hard to catch job for you .

I hope the above information has been helpful , for any further questions please feel free to ask in the comment section below .
.all the best .

Thank you .
