Hello dear aspirant

Hope you’re doing well

Yes its true, you need to have standard maths in class 10th  in order to choose and get science stream in class 11 & 12.

It was just in this session that states allowed students who have opted for Basic Mathematics in Class 10 this year, to opt for the subject in Class 11 without having to write the Standard version of the paper later. This relaxation in policy has been prompted by the sharp rise in cases in the second wave of the COVID-19 pandemic.

if you’re still in 10th then try changing your basic maths to standard maths if you want to pursue science stream in future.

Good luck
