Dear Candidate,

You may find various coaching classes for your subject. You need to interact with the students who have taken the previous maths course by the names you took. Talk with them, ask them about their experience & if they gave enough material and attention to students. You also need to know if the faculty is good for you. Whatever may work for others, may not work for you. Read reviews of the mentioned educators on Quota, and different sites. You will somewhere get close to which educator can give you the best value for money. When you actively search for which thing separates them, you will start finding results as per your preference.

But you will have to invest some time in this.

Thanks.
