CampusO₂ vs Save My Exams: Which Revision Platform is Better for GCSE & A-Level?

A practical comparison of CampusO₂ and Save My Exams for GCSE and A-Level revision: question generation, exam boards, subject coverage, pricing and AI features.

Two different approaches to exam revision

Save My Exams and CampusO₂ both target UK students revising for GCSE and A-Level, but they take fundamentally different approaches. Save My Exams is built around a curated library of past-paper-style questions and notes. CampusO₂ is built around AI-generated practice that produces fresh questions on demand.

Neither is right for every student — this comparison is practical, not promotional.

Question source

Save My Exams uses a fixed, human-curated bank of questions written in past-paper style. The advantage is consistency and quality control. The limitation is that the bank is finite — once you have worked through the available material, you cannot generate more.

CampusO₂ uses AI to generate a unique set of questions every time. You never run out of practice material for the same topic. The trade-off is that AI-generated questions, while specification-aligned, differ in origin from officially released past papers.

Exam board coverage

Both platforms cover AQA, Edexcel, and OCR for GCSE and A-Level. CampusO₂ also supports 11+ (eleven plus) practice (Maths and English), which Save My Exams does not.

Subject coverage

Save My Exams covers a broader range of subjects, including Physics, Geography, History, and more. CampusO₂ currently covers Mathematics, English, Chemistry, and Biology — focusing depth over breadth. If you need Physics or Humanities subjects, Save My Exams has more material today.

AI features

CampusO₂ includes AI explanations for every answer, an AI study guide generated after each attempt, a chatbot tutor available during practice, and an AI essay writing feedback tool. Save My Exams has more limited AI capabilities and is primarily a content library, not an AI tutor.

PDF digitizer

A feature unique to CampusO₂: the Exam Paper Digitizer turns any PDF (past papers, worksheets, school mocks) into an interactive practice exam. Save My Exams does not have an equivalent.

Performance analytics

CampusO₂ provides topic-level performance reports, attempt comparison, and downloadable PDF reports. Save My Exams tracks progress at a higher level.

Pricing

Save My Exams offers a free tier with limited access and a premium subscription. CampusO₂ also offers a free tier with unlimited AI-generated practice — meaning you can generate and attempt as many papers as you want for free, with premium plans unlocking advanced analytics and downloads.

Who should use which?

Use Save My Exams if:

  • You want broad subject coverage (Physics, History, Geography)
  • You prefer human-curated questions with established quality control
  • You are primarily looking for a notes and question bank, not an AI tutor

Use CampusO₂ if:

  • You need unlimited practice beyond available past papers
  • You want an AI tutor that explains answers and builds a personalised study plan
  • You are preparing for 11+ grammar school entrance as well as GCSE/A-Level
  • You want to digitize your own PDFs and worksheets for interactive practice
  • Your subjects are Maths, English, Chemistry, or Biology

Can I use both?

Yes — and many students do. Use official past papers and curated question banks for accuracy benchmarking, and use CampusO₂'s AI generator for the volume of practice needed once those resources are exhausted.
