Hello Sanyam.

Congratulations for your 62% marks, I am sure that you are getting commerce but the only difficulty you are facing can be with the optional subject. it's not impossible for you to get maths as the optional subject. but if your school is not allowing you to take maths as the optional subject, you can try to contact with the teachers and show them your previous maths scores, if they find your good scores in the subject, i m sure they will help you get maths as the optional subject. but if this does not helps, I'll suggest you to take some other optional subject as the teachers actually know what will help us in the future.

Hope you get what you need.

All the very best.
