Hello there! I am sorry my friend, but the minimum marks required for this course are 75% in 12th with PCM and a respective JEE Main score, so with a heavy heart, I have to tell you that you are not eligible, but you can try in other colleges where the eligibility criteria is less or lower percentage is required or you can also try in some private university or college.
Good luck for your future.

Generally, they'll ask about you. Why do you wish to pursue BCA? Have you ever done programming? Do you know any programming languages?

It doesn't matter if you have any experience in programming while pursuing BCA.
