Khan Academy is a non-profit learning platform with video lessons, articles and practice exercises. It is known for clear explanations of school-level maths and science.
The syllabus is not tied to any single Indian board, so use it to understand concepts and keep your textbook as the main source for exam preparation. Language options depend on the topic, so check what is available for your subject.
For note-taking while you learn, see Google Keep or Notion.
Is Khan Academy free? The core lessons and practice are free, and it is run by a non-profit.
Which class levels does it suit? It is strongest for school-level maths and science. Check the course list in the app for your topic.
Khan Academy works best as a second teacher, not a replacement for your school. Its strength is clear, patient explanations that you can repeat as often as needed. Because the content is not tied to any Indian board, use it to understand a concept, then return to your textbook for the exact exam syllabus. Do the practice questions; watching alone gives a false sense of progress.
A Class 9 student did not follow a topic in class. They watch the short lesson, attempt the practice questions, and go back to the textbook with a clear idea of what to ask the teacher.
Pair it with Google Classroom for homework, Google Keep for notes, and Wikipedia for general background reading.
