Sharpen Up
Answer real AQA exam questions and get marked instantly against the real mark scheme — no waiting for a teacher. Every question in Sharpen Up comes from an actual AQA GCSE science past paper, and every mark you're given (or not given) traces back to a marking point on the actual AQA mark scheme.
How it works
- Pick your course (Combined Science: Trilogy, or separate Biology, Chemistry or Physics), your tier, and what you want to work on — a topic, a spec point, a question type or a command word.
- Answer a real past-paper question in your own words, like you would in the exam.
- Sharpen Up marks it on the spot, marking point by marking point — you see exactly which points you hit, which you missed, and what the examiner wanted for each mark.
- Where AQA's examiner reports commented on the question, you see what real students got wrong that year too.
What's inside
Nothing is invented: no AI-generated questions, no paraphrased mark schemes. If Sharpen Up gives you a mark, it's because a real AQA marking point says so.
Why marking yourself changes everything
Most revision is answering questions and never finding out precisely why an answer got 2 out of 4. The mark scheme is where GCSE marks actually live — the difference between "the particles move faster" and "the particles gain kinetic energy" can be a mark. Sharpen Up puts that feedback loop on every single question: answer, see the marking points, close the gap, go again. Target Practice mode lets you drill one spec point or one command word ("explain", "evaluate", "compare") until the marks stick.
