Best GCSE Science Revision Websites
Physics and Maths Tutor is the strongest single starting point for GCSE Science, because it combines free revision notes, worksheets and past-paper questions sorted by topic across Biology, Chemistry and Physics. Revision Library's own science library is the best option specifically for printable worksheet practice with a full mark scheme on every pack, and Save My Exams and Cognito are worth adding for revision notes and video teaching respectively.
This comparison is published by Revision Library, and Revision Library appears on the list below.
How this list was made
This list compares five GCSE Science resources on four things: whether teaching content (notes or video) is included alongside practice, whether a full mark scheme comes with the practice, whether an account is needed, and cost. Every site listed was checked on 30 August 2026.

The full comparison
Physics and Maths Tutor (PMT)
Best for exam-style question sheets by topicPhysics and Maths Tutor (PMT) is a free resource site with revision notes, worksheets and past-paper questions sorted by topic and exam board, across maths, the sciences and several other GCSE/A Level subjects. It also sells separate paid tutoring, crash courses and printed workbooks alongside the free material.
PMT's notes, worksheets and past-paper questions are sorted by topic and exam board across the sciences as well as maths, which suits a student revising one specification point at a time.
Revision Library
Best for free printable practice with mark schemesRevision Library's GCSE Science library covers Biology, Chemistry and Physics as printable worksheet packs, split into the three strands a triple or combined science student actually studies: Biology, Chemistry and Physics. Every pack ends with a full, itemised mark scheme rather than just final answers, and none of it needs an account.
The worksheets hub lists every science pack in one place, each opening as its own indexable page before the PDF. For the method behind a topic rather than just the practice, the matching science topic guides work through a definition and a worked example first, including the required-practical write-ups that GCSE science exams draw questions from directly.
For a student combining topics across a whole unit, the Science Pack Builder stitches any combination into one PDF, and past-paper practice by topic complements it for revision closer to the exam. The free book shelf does the same job for a whole strand in one ready-made download.
Two examples of what a pack actually contains: Cell Biology and Atomic Structure and the Periodic Table, both exam-style questions with a full mark scheme at the back.

Cognito's video-led lessons and large quiz bank suit a student who wants the science explained before attempting questions, and none of it needs an account.

How to choose
If the exam is close and the gap is practice rather than teaching, a free printable pack with a full mark scheme, like Revision Library's, gets a student marking their own work the fastest.
If a topic has not been taught well or was missed, start with notes or a video before the questions - PMT's written notes and Cognito's videos both work well for that first pass.
Required practicals come up as written exam questions on every board, so treat them as a normal revision topic rather than something only done once in a science lesson.
Whatever the source, practise across all three sciences rather than the one a student finds hardest - combined science papers mix topics, and triple science students are examined on all three separately.
