Hello,

If you had basic maths in Class 10 CBSE, then officially you are not eligible to take PCM (Physics, Chemistry, Maths) in Class 11. For PCM, schools usually ask for standard maths in Class 10.

But still, some schools may allow you if your overall performance is good and if they feel you can manage. So, it mainly depends on the school's decision .

It’s better to talk to your school once and check what they allow.

Hope it helps !
