Hello Rishit

I hope you are doing good.

Before anwering this query , I would like to introduce myself first . I have scored 500rank in national level exam and currently perusing mca from nit jamshedpur . So for getting admission into mca you have to exam of nimcet for tier-1 colleges, for that you should have 60 percent marks in your bachelors of computer applications . You can do bca after commerce stream even if you have maths subject. I would like to suggest you right focus on your 10+2 and explore some better options too.

Hope you found this answer helpful. Good luck for your future
