A simple revision routine
Read the chapter explanation, copy the important symbols and units into your own notes, and work through an example without looking at its solution. Try the practice, check the explanation, then revisit the part that caused difficulty.
Current coverage
English-medium Physics revision for selected topics from Chapters 1–3 is available. The collection is a growing set of resources, not a claim that every Class 9 subject or textbook exercise has been covered.
