cs and cfa are both different courses and both require an equal amount of hard work. You must do your part of primary and secondary research and then you can decide whether you would want to pursue CA or CFA. Math is not only one factor that you must consider, you should consider multiple other factors as well. You can start by making a pro and con list, that may help you decide it better according to your needs.
Hope it helps!
