After every classroom lecture or textbook reading, use the notes for a quick revision of the same topic. This helps reinforce learning and improves retention. Break down your revision into smaller chunks. For instance, revise one or two chapters per week using the notes, and mark important concepts or formulas that you need to revise more often. Use sticky notes, highlighters, or bookmarks to keep track of difficult sections. Before exams, rely on the notes for last-minute preparation. Focus more on derivations, numerical formulas, and conceptual questions—these form the backbone of Physics exam papers. Also, try solving previous years' board questions and sample papers using only your notes as a reference. Using notes alongside your NCERT textbook ensures you don’t miss out on any topic. Combine this with regular practice and mock tests, and your exam preparation will be more efficient and stress-free.
