Yes for sure, if you're asking that you didn't have maths in your 10+2 but want to get into BCA. But in place of that, you'll need to have Computer Science/Statistics/Computer Applications. And there will be mathematics in at least 4 out of 6 semesters in BCA, so you will have to study well to secure good marks. All depends on you that how you study. All the best.
