how to prepare maths jee main and advanced

To prepare JEE Mains and Advanced Mathematics you really need to devote a lot of time in practice because in Mathematics only knowing of concepts don't work because if you are quite good in Calculus but your concepts of Trigonometry are not that good them you might get stumbled on a question. And not only that, only knowing concept isn't sufficient..but being thorough with it is very very important.
So the best thing you should do is firstly be clear with what you know well and what you don't and according to that you should decide your priority. For instance you must know that the total JEE Mathematics has been divided into 5 parts -

1. Algebra
   
2. Trigonometry
   
3. Calculus
   
4. Co-ordinate Geometry
   
5. Vector & 3D Geometry

Among this 5 you should firstly have a clear idea about which topics you are well aware of...your strength and weaknesses..
You can start with any of them and then go in deep of every chapters and concepts. Keep one thing in mind that Trigonometry is very very important because it has its use everywhere. It can be mixed with any of the other topics. So you really need to master it then only you can solve Advance level problems.
Once you have got a deep knowledge of a chapter and you have solved plenty of questions then you should go for previous year questions. They are a must to solve because they give you idea of what type of questions are asked in JEE.
This strategy is really helpful if you have a lot of dedication and if you are hard working.
Thank you.

Hello sagar,
The preparation of the maths jee main and advanced should be a conceptual way. Every problem you're solving you must think it in conceptual way rather concentrating on the given values or else same model.
Only thing you remember is prepare maths always in conceptual way. And listen up your classes wisley
All the best
