Hello dear

Of course biology students can do BCA but the problem comes in doing it from renowned universities and colleges as they give it to maths students only , but don't lose hope there are lots of average universities and colleges from where you can do it but I have a suggestion if you want to do BCA go once through class 11 and 12 maths book at least go through NCERT to clear basic maths level of 11 and 12 as you are a bio student and might face problem if you don't study maths now.

Thankyou
