Instant, mark-scheme-accurate feedback. For every answer. Every subject. Any time.
EC2 Excel gives GCSE and iGCSE students instant, mark-scheme-accurate feedback on their exam answers — so every practice session counts.
Who it's for
If you're in Year 10 or 11, you already know the drill: past papers are the best revision there is. The problem has always been getting feedback fast enough to act on it. Waiting for a teacher to mark a stack of papers takes days. Tutors are expensive. Marking yourself is better than nothing — but it's hard to be objective about your own work.
EC2 Excel solves that. Photograph your handwritten answer. Get a breakdown of every mark — what you earned, what you missed, and what a stronger answer would include — in seconds. Official mark schemes. Real examiner logic. No waiting.
It's designed for independent use, though parents often find it just as useful for tracking progress between school reports.
Meet Professor Shelly
Professor Shelly is EC2 Excel's AI examiner — trained on official mark schemes and examiner reports from Edexcel, Cambridge, AQA, and OCR. She knows exactly what examiners are looking for, because she's built from the same materials they use.
Shelly doesn't let things slide. She'll catch the mark you nearly earned but didn't quite justify. She'll point out the argument that was almost there but missed the command word. She marks the way a real examiner does — methodically, point by point, against the mark scheme — because that's the only kind of feedback that actually prepares you for the real thing.
But here's the difference: she also wants you to get there. Every piece of feedback comes with a clear explanation of why — not just what you missed, but what a stronger answer looks like and how to close the gap. She doesn't penalise effort; she rewards understanding. Make progress and she'll notice. Keep showing up and she'll keep pushing you forward.
Think of her as the teacher who holds you to a high standard because they know you're capable of meeting it — available any time, never impatient, and always focused on turning your next attempt into a better one.
She's not here to replace your teacher. She's here to make every hour between lessons count.
Why it works
Decades of learning research point to the same thing: retrieval practice — testing yourself, then reviewing what you got wrong — is one of the most effective ways to learn. Not highlighting. Not re-reading. Doing, then understanding why.
EC2 Excel is built on that idea. Every grading session is a feedback loop: attempt, submit, understand, improve. Students who use it consistently don't just practise more — they practise smarter.
