Save My Exams vs OnMaths: Feature Comparison

Save My Exams and OnMaths both offer plenty of Maths exam practice, but the way you use the two platforms is quite different.

Revision Notes and Content Quality

Save My Exams provides specification-aligned revision notes written by experienced teachers and examiners. You'll also find flashcards and exam-style questions with worked solutions and exemplar answers. Past papers help you apply what you’ve learned in exam conditions.

AI-powered tools can provide extra support on selected courses. Revision Note Chat can explain concepts or generate questions from the notes. Guided Study takes you through a topic step by step.

OnMaths takes a more practice-led approach. If you prefer to learn by doing, you can choose a Maths topic and start answering questions.

If you get stuck, an Ultimate subscription gives you full working and video explanations for questions across the site. OnMaths also provides GCSE revision courses and exam walkthroughs, so question practice isn't the only way to learn.

Exam Board and Specification Coverage

One of Save My Exams' main strengths is its exam-board-specific approach. Resources are organised by qualification, exam board, subject and topic, helping you focus only on the content included in your course.

OnMaths provides GCSE Maths practice for Edexcel, AQA, OCR and Eduqas. Its predicted-paper collections are organised by exam board, tier and paper, giving you practice designed to reflect the format and style of your GCSE exams.

Practice Questions and Exam Technique

Practice is one of the biggest strengths of both platforms.

Save My Exams provides structured exam practice through topic questions, exam-style questions, worked solutions, past papers and mock exams. These resources help you understand how marks are awarded and develop your exam technique.

OnMaths gives you several different ways to practise depending on how much time you have and what you want to work on. Topic papers let you target a particular area, while Mini-Mocks provide around 20 minutes of timed practice.

You can also work through full predicted papers designed to reflect real GCSE Maths exams. Demon Papers offer a tougher challenge. Revisionator is useful when you've only got 10 or 15 minutes and want a quick burst of randomised practice.

Personalisation and Study Support

Save My Exams helps you focus your revision through tools such as Smart Mark, Strengths & Weaknesses and Guided Practice. Study Planner provides further support.

These tools can help you spot knowledge gaps and target weaker topics. They can also help you decide what to revise next.

OnMaths lets you choose practice by topic, tier and type of paper. Its self-marking papers give you results straight away. With a free account, your scores are saved so you can keep track of how you're doing.

Revisionator offers another way to target your practice. You can choose different grade ranges and topic collections, then work through randomised multiple-choice questions. This is useful when you want to revisit a topic without simply repeating the same paper.

Ease of Use and Student Experience

Save My Exams organises resources by qualification, exam board, subject and topic, making it straightforward to find the resources you need. The structured layout is particularly useful when you're revising an entire course or preparing for multiple exams.

OnMaths makes it easy to get straight into Maths practice. You don't need an account to access its papers, but creating a free account allows you to save your scores.

You can choose between Foundation and Higher GCSE resources, individual topics and different types of practice paper. It's easy to find something that fits the time you have, from a short Revisionator session to a longer exam-style paper.
