First of all, Maths is a very good subject. Score well in your class 12th for eligibility of JEE Mains, or you can try doing B.Sc in Maths.

You can definitely prepare for CAT and if you prepare well you might even get 99+percentile. But, even then getting into an IIM will be quite difficult, because they give a significant weightage to your past academics as well.
