Common SL Revision Problems
Struggling to explain a definition
Use each term in a complete biological explanation and connect it to the question being asked.
Spending too long rereading
Test recall first, then return to notes when a question reveals a specific gap.
Forgetting earlier topics
Rotate between recent material and older syllabus areas to practise retrieval over time.
Misreading the question
Identify the command term and distinguish between stating, describing and explaining.
