Copying everything usually wastes time. Read the note, then write a shorter version from memory: equations, definitions, diagrams, common mistakes and one worked method you need to remember

Close the note and explain the idea without reading, reproduce the key equations and then solve unfamiliar questions. If you can only recognise the content while reading, the chapter is not yet secure.

Yes, especially where students commonly lose method marks. Worked examples should show how to choose the equation, rearrange it, use units correctly and present the answer with sensible precision.

Use diagrams and representations actively. Draw wave features, relate them to equations, practise phase or superposition ideas and then solve questions that combine graphical and calculation reasoning.

Move into topical questions as soon as you can explain the chapter and use its core equations. Do not wait until every chapter is perfect before beginning exam-style practice.
