Long questions are answered by decoding what is asked, planning your key points, and
writing them precisely with no essays, no waffle. Section C is 60% of the paper, so this is
where an H1 is won.
But technique only pays off if the preparation is there. We will cover both: how to build the
subject, then how to write the answer.
The Revision Loop: Understand the Concept → Verify with Past Papers → Identify Gaps →
Fix the Mistake → Practise Again.
Preparing the Subject
- Focus on the Mechanism: Understand and build your concepts,do not just blindly
memorise. - Target High-Yield Units: Strategically spend your energy on the units that dominate
Section C year after year. - Test Early: The moment you finish a topic, verify your understanding using actual
previous-year questions. - Close the Gaps: Identify your mistakes, find out why you got them wrong, and actively
fix the misunderstanding before moving on.
Before You Write (Understanding + Planning)
- The Double-Read: Read the question carefully, twice.
- Filter the Noise: Long questions provide a broad experimental context. Understand that
context, then focus on the real question: WHAT is actually being asked? - Don’t Panic at the Length: Take the question part by part. Break it down into sub-
questions. - Decode the Command Words:
◦ State / Name / Give → One or two words max.
◦ Outline → Give the main points, briefly.
◦ Describe → State what happens, step by step.
◦ Explain → State why or how it happens scientifically.
◦ Compare → Give similarities and differences, linked in the same sentence using
“whereas” or “while”. - Margin Notes: Jot down your key scientific terminology in the margin before you start
writing your full answer.
Writing the Answer (Structure + Terminology)
- Lead with the Core Idea: Write one direct sentence that answers the prompt
immediately. - Follow the Process: Structure your answer logically — Core Idea → Step-by-Step
Process → Conclusion. - Make Grading Easy: Break your response into clean, distinct bullet points so the
examiner can tick off marks effortlessly. - Signpost Your Keywords: Underline your key scientific terms in pen to draw the
examiner’s eye straight to your marking points. Keep pencil for diagrams only. - Use Scientific Terminology: Use the scientific word wherever one exists it is what the
marking scheme credits.
Instead of writing… Use the scientific term
Breaking something down with water Hydrolysis
The shape changes / melts Denatures
Speeds the reaction up Catalyses
Winning the Marks (Exam Technique + Pitfalls)
- Pencil Only for Diagrams: Include large, well-labelled diagrams drawn in pencil. An
unlabelled diagram scores zero. - No Double-Dipping: Do not repeat your points. Saying the same idea in two different
ways earns the mark only once. - Watch the Spelling: Misspelling specific terms (like glycolysis or glucagon) can cost
you the mark as it alters the meaning. - Never Scribble: If your order is wrong, do not aggressively cross it out into an
unreadable mess. Neatly draw a line through it, rewrite it in the correct order, and only do
this if you have spare time. - Bank the Sure Marks: Mind your time. Do not linger on questions you are unsure of.
Answer what you know first, then circle back to the harder parts. - Logistics Matter: Bring full stationery on the day — spare pens, sharpened pencils, a
rubber, and a ruler. Do not rely on your neighbors.
Final Thoughts - Three things decide the grade: Structure, Precision, and Exam technique. Know the
biology, answer exactly what is asked, use the right terms, and set it out cleanly — the
marks follow. - Work through past papers, then grade yourself against the official marking schemes.
Nothing teaches you faster what the examiner actually credits as a key point. - Stay calm. Remove the panic and the anxiety. You know the material, your only job now
is to deliver it strategically. - Sleep well the night before. A rested brain will always score higher than a crammed
one.
