AI-powered scoring and revision support.
MCQ scoring · AI-guided review · Structured Q grading (AI-assisted)
Write your answer, and we'll show you exactly which marks you earned — and how to rewrite the rest for full marks. Turn every gap into a revision target you can act on.
✓ 1 mark “Active transport requires ATP because it moves ions against the concentration gradient...”
✗ 0 marks “It uses energy to move things across the membrane.”
→ Rewrite: “Carrier proteins use energy from ATP hydrolysis to transport specific ions against their concentration gradient.”
△ partial “The sodium-potassium pump moves Na⁺ out and K⁺ in...”
→ Add: mention the 3:2 ratio and that this maintains the resting potential
Your Top Misconception:
You consistently confuse facilitated diffusion with active transport — choosing options that describe energy-requiring processes when the question describes passive movement.
Every wrong answer reveals a thinking pattern. We analyse each option to find the specific misconception behind your choice — so you fix the root cause, not just memorise the right answer.
Answer a few questions. Get a daily revision plan built around your timeline, your gaps, and how much time you have. It adapts as you improve — so you never revise the wrong thing.
Less than the cost of one tutoring session — with scoring that never sleeps.

Currently: Cambridge International AS & A Level Biology (9700). You get automatic MCQ scoring (Paper 1, answer-key based), AI-assisted marking for structured questions using Cambridge command-term conventions, and AI-guided topic reviews across all 19 syllabus topics. More Cambridge syllabi coming soon. Looking for AP? Visit our AP page.
For Paper 1 MCQ, scoring is deterministic against the published answer key. For structured questions (Papers 2/3/4/5), we do not ship official Cambridge mark schemes — instead, an AI examiner evaluates your answer against standard Cambridge command-term conventions (state, explain, suggest, evaluate) and shows you which marks you likely earned and how to rewrite for full credit. Treat AI-assisted marks as a coaching aid, not an official result.
We accept Visa, Mastercard, American Express, WeChat Pay, Alipay, Apple Pay, and Google Pay through Stripe's secure payment platform.
