Is math subject is important for the course BCA / MCA ?
Hi Kunal,
No, its not compulsary to study Maths before the BCA/MCA course but if you have maths, then it is not any harm in that. It is only an add-on to have maths in 12th before pursuing BCA or during BCA studying Maths will help you in programming and several other computational calculation works.
