Does this work for Biology, Chemistry, and Physics?

Yes. The AI provides feedback on 6-mark extended writing questions from all three Science disciplines. It recognises subject-specific terminology and marking expectations for each.

How are 6-mark questions marked in Science?

AQA uses a levels-based mark scheme for 6-mark questions: Level 3 (5-6 marks) requires detailed, logically structured responses with correct scientific terminology; Level 2 (3-4 marks) for answers with some relevant points but lacking structure or detail; Level 1 (1-2 marks) for simple statements with limited scientific vocabulary. Our AI assesses against these same level descriptors.

Does the AI check for correct scientific accuracy?

Yes. The AI checks for accurate scientific content — correct definitions, valid cause-and-effect chains, and proper use of terminology. It will flag common misconceptions such as confusing heat and temperature, or stating that evolution happens "because organisms need to adapt."

Can I upload handwritten Science answers?

Yes. Our OCR technology reads handwritten work from photos, including diagrams and equations. Take a clear photo of your response and upload it for instant feedback.

Is this suitable for Combined Science and Separate Sciences?

Yes. The 6-mark extended writing question format and the marking criteria are consistent across both Combined Science (Trilogy) and Separate Science (Biology, Chemistry, Physics) papers.

What about required practical questions?

The AI can assess extended responses about required practicals — including experimental design, method descriptions, and evaluation of results. It checks for understanding of variables, accuracy, and precision in your explanations.

Instant AI Feedback for GCSE Science Extended Writing

Upload your handwritten or typed 6-mark Science response and get detailed, AQA-aligned feedback in seconds. See exactly how your scientific knowledge, application, and quality of written communication score against the mark scheme.

GCSE Science exams include extended writing questions worth 6 marks that require students to construct detailed, logically structured scientific explanations. These questions appear across Biology, Chemistry, and Physics papers and test whether students can link scientific concepts, use precise terminology, and communicate their reasoning clearly. Many students lose marks not because they lack knowledge, but because they fail to structure their answers logically or miss key scientific details. ReMarkAble AI provides instant feedback on the quality of scientific explanation, use of terminology, logical structure, and completeness of response.

Tips for Science (Extended Writing)

1. Plan before you write

The 6-mark question rewards logical structure. Before writing, jot down 3-4 key points you need to cover. Then arrange them in a logical order — cause before effect, process steps in sequence, or general principle before specific example. A well-structured answer scores higher than one with more content but poor organisation.

2. Use precise scientific terminology

Examiners look for correct use of key terms. Write "mitosis" not "cell splitting," "rate of reaction" not "how fast it goes," and "gravitational potential energy" not "stored energy from height." Each correct scientific term demonstrates AO1 knowledge and can earn marks even in otherwise weaker answers.

3. Link cause and effect explicitly

The most common weakness in Science extended writing is failing to explain why. "Temperature increases so rate of reaction increases" misses the mechanism. "Increasing temperature gives particles more kinetic energy, so they collide more frequently and with greater energy, meaning more collisions exceed the activation energy, increasing the rate of reaction" makes the causal chain explicit.

4. Cover all parts of the question

Many 6-mark questions have multiple parts embedded in one prompt — "Describe how... and explain why..." Make sure you address both the description and the explanation. Read the question twice and underline command words to ensure you cover everything the examiner is looking for.

5. Include data or numbers where relevant

If the question provides data (a graph, table, or values), refer to it explicitly in your answer. "The graph shows that at 40°C the rate of reaction doubled compared to 20°C" is much stronger than "the rate increased with temperature." Quantitative reference demonstrates AO2 application skills.
