How to work through IGCSE Biology
- Work in syllabus order. Topics 1 to 5 supply the cell and enzyme vocabulary that every later topic assumes.
- Learn the definitions word for word. Biology awards more marks for precise wording than any other science.
- For every adaptation question, write the feature and then what it achieves. The link is where the mark sits.
- Build one table per topic: enzymes, blood vessels, plant minerals. Most recall marks come straight off those tables.
