How to Get a 7 in IB Biology: Tips From Top Students
Introduction
IB Biology is one of the most challenging sciences in the Diploma Programme but it's also one of the most rewarding. If you're aiming for a 7, you'll need more than just memorisation. You'll need a strategy that combines syllabus mastery, exam technique, and smart revision habits.
Here are proven tips from students who scored top marks in IB Biology.
1. Learn the Command Terms Inside Out
IB examiners are strict about command terms like explain, distinguish, evaluate, and compare. A 7-level answer always tailors the response to the command term.
- "Explain" = show cause and effect
- "Evaluate" = weigh up strengths and limitations
- "Outline" = keep it short, clear, and structured
Before every practice, check you've actually followed the command term.
2. Revise With the Syllabus, Not Just Notes
The IB syllabus is your roadmap. Everything on the exam comes from those dot points.
- Print or download the syllabus
- Check off concepts as you revise them
- Turn each dot point into a potential quiz question
With Study Marker, you can generate quizzes directly from IB Biology syllabus points to make sure you cover everything.
3. Use Diagrams Effectively
In biology, a neat diagram can sometimes say more than a paragraph. Practice drawing:
- Cell ultrastructure
- Photosynthesis/respiration pathways
- Circulatory and nervous systems
Examiners love accurate, labelled diagrams — they show real understanding.
4. Do Past Papers Under Timed Conditions
It's not enough to "know the content." You need to practice applying it under pressure.
- Do at least 5-6 timed past papers
- Review mark schemes - learn what examiners reward
- Keep answers concise and structured
5. Get Feedback on Your Practice
Top students don't just practice - they refine. Submitting practice short answers and essays for feedback is the fastest way to level up.
Study Marker lets you upload a response and get instant feedback on clarity, accuracy, and structure.
Final Tip
A 7 in IB Biology isn't about luck. It's about methodical preparation, constant practice, and smart use of resources.
