Hello Aspirant,

See usually Mathematics subject is compulsory till class 10th among all boards but even if you don't had that or you have not studied Mathematics in class 10th then also you can get admission in PCB stream in class 11th but note that in CBSE board if you want to opt for Mathematics as well either as an additional subject or main subject along with Biology as an additional subject then you should have Standard Mathematics in class 10th otherwise you want to go for any other stream than science in class 11th then you can also appear for Basic Mathematics in class 10th but Mathematics is compulsory subject till 10th at least.

I hope this information helps you.

Good Luck!!
