Revision methods
Check understanding by explaining a concept plainly
Explain the idea with an example, then test whether the explanation remains accurate when the situation changes.
Choose a specific listener and question
Imagine explaining one course concept to a classmate who missed the lesson. Decide what they need to understand. Avoid choosing an entire unit. Write the explanation without leaning on undefined technical words, but keep terms that are essential and define them clearly.
Include the mechanism
A label is not an explanation. For a process, describe what changes and why. For a mathematical rule, show where it applies. For an argument, connect the claim to evidence. When you notice yourself saying “it just happens,” mark the gap and return to a reliable explanation.
A percentage example
To explain a 20% discount on an item priced at 500, state that 20% means 20 out of every 100. The reduction is 0.20 × 500 = 100, so the new price is 400. Then change the question: increasing 400 by 20% gives 480, not 500, because the base is now different. This variation checks whether the explanation includes the role of the starting amount.
Check the limits
Compare your explanation with course materials and try an unfamiliar example. An analogy can help introduce an idea but may stop working outside a narrow case. Say where it breaks down. If another person listens, invite them to point out unclear steps rather than simply agreeing that it sounds good. Keep the revised explanation as a study note, with unresolved questions clearly marked.
