Dear aspirant,

Let me tell you that as you have mentioned that you have studied pcb in class 12 and considering you haven't studied maths or you didn't have maths as your subject so you for jee mains it is mandatory to have maths physics as your compulsory subjects.

So if you want to give maths as reappearing student and if it is possible in your board then you should go for it.

But you should first talk to your school about this whether this is possible or not .
