Hello student I request you to please help me with the examination you're concerned about so that I can check and provide you the exact information how you can score 50 Mark's or above in the same.

Prefer NCERT to build your basic concept and make sure you do each and every example and exercise questions of Ncert before jumping to a reference book, after completing ncert thoroughly refer to the reference book as mentioned below -

Rd Sharma Mathematics

Rs agarwal mathematics

Arihant practice book.

Feel free to comment if you have any doubt

Good luck
