"Is Hindi Mandatory in ISC Class 11 Science Stream? Exploring Optional Subject Choices"

"I'm considering enrolling in the ISC curriculum for Class 11 with a focus on the science stream, including subjects like Mathematics. I would like to know if Hindi is a compulsory subject in this stream. If Hindi is not mandatory, what are the alternative subjects that students can opt for instead? Additionally, are there any specific guidelines or restrictions on choosing these optional subjects? Any insights or experiences would be greatly appreciated."
