As you are not from the Non- CS background the first problem you will face is regarding the study procedure of CS. CS contains mainly Discrete Mathematics & as you don't have much exposure about that it can be a problem for you. But this problem can easily be resolved as Discrete Mathematics is mostly logical & if you have good logical sense, it would just be a candy for you. The second problem might be the coding exposure. If you have no coding background, then going into the course can feel intermediating but again, if you are sincere about the studies, then this will not be much of a problem. So if you are going for MCA, you should be ready to do some hardwork & believe me it would take you 1 semester to get accustomed with the terminologies & skill sets. So don't get very tensed, if you are interested just pursue it.

I hope this helps. Wish you a Great day!
