11th Science in math cancel can apply in 12th science math ?
Hello student if the examination is cancelled by the authorities (school or board of education) then the result must be evaluated on internal assessment and in that case yes you can continue Maths in class 12 as registration for class 12 gets completed in class 11 itself and subject as per student choice submitted to the board of education.
Feel free to comment if you have any doubt
Good luck
