Hi Aishwaya,

The code for CBSE 12th Mathematics is 041.

But I would refer you to visit your School once and have a talk with your teacher they will guide you better.

Do the NCERT book and the chapters which will easily pass you are:-

1-Probability.

2-Relation and Function.

3-Linear Programing.

4-Matrices and Determinant.

5-ITF.

6-Vector Algebra.

7-Continuity and differentiability.

8-AOD is not hard.

These chapters will easily pass you.

Hope this will help,please feel free to ask if you have any further queries.

Thank You.
