Hello,
I hope you are doing well, It depends which CS you are talking about. If you are talking about CS (Company Secretary) which is related to commerce stream then Maths is not compulsory in this course but if you are talking about CS(Computer Science) Then there would be maths as a subject. It may vary college to college. In some colleges they keep maths till first year and in some till last year. So yeah there would be Maths in Computer Science.
I hope you find this information helpful. I wish you all the best for your future.
Good Luck
