If you haven’t started revising for your GCSE biology, you should start now. You can use my biology revision page as a checklist. Just copy and print the text; then write down a date against each major topic so you can keep track of your progress. Now make some marks to indicate:
- What you have understood and memorised (no further work needed),
- What you have understood but need to memorise,
- What you don’t understand and need to do some more reading,
- What you need a teacher’s help with.
Register on my website’s biology section, login and then use one of the comment forms to ask your question. It is totally free!
