Cognito vs Save My Exams: A full comparison for GCSE and A-Level students

Cognito and Save My Exams both help students prepare for exams, but they cover different parts of the picture. Cognito is a full study platform: animated video lessons, exam-board-mapped notes and built-in quizzes, flashcards and exam questions that help you retain what you've learned. Save My Exams is a written revision library built around examiner-authored notes, topic questions and past papers.

Cognito is designed to be an all-in-one platform that supports you from learning the content, to remembering it, to knowing how to apply it in your exams. So when you sign up, you can add all of your subjects to your dashboard, ready to go, as you can see below.

Each subject is broken down into sections and subtopics, all mapped precisely to your specification. That means you only ever learn what you actually need to know for your paper, and you can see at a glance what's left to cover.

Each topic has a short video lesson and/or beautifully designed revision notes, and some have a little cheat sheet that summarises everything on one page. It's good for last-minute revision, or printing out and sticking on the wall.

Once you've learned a topic, you can build your own quiz mixing any set of topics you've covered. Cognito uses spaced repetition and interleaving to decide what to bring back and when, adapting to how you're doing. These are the two study techniques with the strongest evidence base in cognitive science.

And when you're ready for exam-style practice, you can work through real exam questions with typed answers. Then either self-mark against the mark scheme point by point, or use AI marking to check your answer against the examiner's points.

A feature-by-feature summary of how the two platforms compare.

Save My Exams is a UK-founded online revision library covering GCSE, IGCSE, O-Level, AS, A-Level, IB and AP across the main UK and international exam boards. The core of the product is examiner-written revision notes, topic-organised exam questions, past papers with mark schemes, flashcards and model answers. Free tier plus a paid Premium subscription at around £48 a year.

Strengths. Exam-board and qualification coverage is one of the widest around, especially for students on Cambridge International alongside AQA, Edexcel and OCR. Notes and topic questions are written by teachers and examiners, so they map closely to what mark schemes are looking for, and the past paper archive is deep.

Where it's less strong. Teaching is text-first, so if you learn better by watching a topic explained on screen with diagrams, there isn't much video to lean on. There's no adaptive practice or AI marking on written answers as headline features, so the active-recall side is closer to a static workbook.

Honestly, the best move is to find what works for you, and it doesn't have to be all or nothing. Plenty of students end up using one platform for one subject and something else for another.

What's great is that both have free content you can try. Cognito's videos and notes are free across every subject, with weekly caps on flashcards and exam questions. Save My Exams has a partial free tier covering some notes and past papers before the annual plan kicks in at around £48.

Broadly, Cognito will be a better fit if you want video teaching alongside notes, active recall and AI-marked exam practice at a single low monthly price. Save My Exams is worth a look if you want deep examiner-written notes tied precisely to a specific board, especially Cambridge International.
