What is inside Pack 2?

Build your skills one topic at a time across QCE Biology Units 3 and 4, then bring them together in checks and mixed revision.

• 18 topic sets with worked support, independent practice and self-checks.
• Two course checks and mixed revision, with the actual chapter counts listed below.
• Course-specific resource conditions stated in the question booklet.
• A printable skill review sheet to record what to revisit.
• Worked solutions, marking criteria, common errors and suggested next steps.

The 90-question total includes topic self-checks, course checks and mixed revision. The 18 worked examples are additional learning support.

Two PDFs in the pack

The question booklet and separate solutions booklet use matching question references.

How to use this resource

1. Start with a topic you are learning at school. You do not need to finish the whole course first.
2. Review the topic prerequisites and worked example. Attempt its practice questions, then the final self-check independently.
3. Use the separate solutions and marking guidance to check your reasoning and record a next step on your review sheet.
4. If you want a starting check, try Check 1 on topics you have already studied before viewing its solutions. Record untaught material as “Not yet studied”.
5. Return to mixed revision and Check 2 as you cover more topics and complete directed practice. Compare your independent work on the selected topics.

This is self-marked topic practice for Year 12 QCE Biology. Use it alongside your school materials. Practice marks are a review aid and do not predict an assessment grade or ATAR.
