Hello,

First of all, you need to register yourself for the CMA foundation exam on their official website and fees for it is around Rs 1200 and after the registration, you'll receive the books from the board itself. You need not join any CMA coaching as there are multiple youtube channels available for them and you can study everything from there itself. You should focus on the important topics and thoroughly clear all your doubts. Solving previous year's question papers which you can find anywhere online will definitely help you clear the exam.

I hope this helps,

All the best
