How to answer six-mark questions

Six-mark questions reward a clear, linked explanation, not the longest answer on the page.

Key takeaways

1. How they’re marked

In GCSE sciences, six-mark extended-response questions are usually marked in levels: Level 1 (1 to 2 marks), Level 2 (3 to 4 marks) and Level 3 (5 to 6 marks). The examiner reads the whole answer and judges how complete, accurate and logically linked it is.[1]

Check the mark schemes for your own subject and board: the idea of levels is common across many subjects, but the details differ.[1]

2. A one-minute plan

Before writing, jot down the four to six points you want to make in the margin, then number them in a logical order. For a process, that is the order things happen; for an evaluation, it’s points for, points against, then your judgement.

Points

Four to six relevant facts or ideas.

Order

Number them so each leads to the next.

Links

Join them with “so”, “which means” or “because”.

3. Write it in a chain

A Level 3 answer reads like a chain: each point leads to the next. Compare a list (“The heart pumps. Arteries carry blood. Oxygen goes to cells.”) with a chain (“The ventricles contract, which forces blood into the arteries, so oxygenated blood reaches the body’s cells for respiration.”).

Lists earn marks. Chains earn levels.

4. Check before you move on

Read the question again. Have you done what the command word asks? Have you used any data or context given? Have you used the key scientific words correctly? These three checks catch most lost marks.

For parents: Ask your child to explain a process to you out loud in order. If you can follow it, an examiner can too.

Answer in your head first, then check.

  1. 1. How many marks is each level worth in a typical six-mark science question?

  2. 2. What separates a Level 3 answer from a list of facts?

  3. 3. What three checks should you do before moving on?

  • Find two six-mark questions from past papers in one subject.
  • Plan each in one minute before writing.
  • Mark them against the levels in the mark scheme.
