The study companion built from the real GCSE & IGCSE exams.
EC2 Excel gives GCSE & IGCSE students daily practice, revision notes for every topic, and instant AI grading against the real mark scheme — so every session of revision counts.
Who it's for
If you're in Year 10 or 11, you already know the drill: consistent practice and past papers are the best revision there is. The problem has always been keeping it up and 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 hard to be objective about.
EC2 Excel solves that. Practise a little every day, revise any topic with clear notes and quick quizzes, then photograph a full paper for instant AI grading — a breakdown of every mark, 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 Sheldon
Professor Sheldon is EC2 Excel's AI examiner — trained on official mark schemes and examiner reports from Edexcel and Cambridge. They know exactly what examiners are looking for, because they're built from the same materials those examiners use.
Sheldon doesn't let things slide. They'll catch the mark you nearly earned but didn't quite justify. They'll point out the argument that was almost there but missed the command word. They mark 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: they also want 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. They don't penalise effort; they reward understanding. Make progress and they'll notice. Keep showing up and they'll keep pushing you forward.
Think of them 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.
They're not here to replace your teacher. They're here to make every hour between lessons count — guiding your daily practice, pointing you to the right revision notes, and marking your papers like the real thing.
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.
