Primary School Content in Hindi

My younger brother studies in class 4th. He wants to learn maths from Khan Academy but sadly he is unable to do so. He is a primary school student. He doesn't understand enough English to watch these videos, let alone American English accent (we're from India)

I request you to make your math, science and other courses available in Hindi, so that the kids can understand. The tests are good in English, because the school tests are in english too. But at most Indian schools, teachers teach in Hindi or Hinglish to be specific. By Hinglish, I mean teachers speak daily use hindi, but the academic terms are used in English. (e.g. The teacher will use the word climate change and will explain what it is in hindi) Your Indian Team will understand all that stuff.

Plz upload hindi courses as soon as possible. Thanks.
