Classes are where the chapter sits in each book, not a limit. A lesson can help a class earlier or later. Matriculation schools use the Samacheer Kalvi books, so they follow that column.

Where to start
Not sure which class to start from?
The starting check asks a few questions on one topic. When an answer shows a gap, it works back to the ideas underneath until it finds where to begin.
