BBC Bitesize
Best for: finding an explanation before you attempt a question. BBC Bitesize has free study support for UK pupils, with content organised by school stage and nation.
For a pupil choosing a main revision site, this is a better starting point than our short games. Open its GCSE science pages and select the material relevant to your course. You can read open content without signing in. An optional My Bitesize account lets you save items.
Give each visit a question to answer. If you cannot explain an idea from your exercise book, read the relevant topic and write your own explanation. A parent can ask the pupil to describe it without looking at the screen. That reveals more than asking whether they have finished reading.
Choose this if you want free course explanations and can decide which topic needs attention.
Seneca Learning
Best for: following a course through content and questions. Seneca Learning has biology, chemistry and physics courses, including GCSE material and an exam-board selector. Your exam board is the organisation setting your papers; ask school which one you follow.
Seneca suits revision across the course better than repeating our single-skill games. Use its course structure to move beyond the topics you already like. After answering questions, keep a short note of what you need to revisit and bring any stubborn confusion to your teacher.
Some features and content sit outside free access. Teachers can set automatically marked homework free, according to Seneca's teacher page. The platform centres on pupil accounts and joining classes, so follow school instructions if your teacher sets work there. Decide whether the free material meets your needs before considering paid access.
Choose this if you prefer a course with questions to choosing separate explanations yourself.
Educake
Best for: science access your school pays for. Educake's pricing page lists science at GBP 880 a year plus VAT for schools. It covers KS3 and GCSE courses including AQA, Edexcel, OCR Gateway, WJEC and CCEA. Pupils use a Student login.
For families, start by asking whether school already subscribes and how you should get access. Keep teacher-set work in the revision timetable so you can discuss difficult topics in class. You do not need to choose another site simply because friends use one.
For departments comparing homework tracking, ask Educake to demonstrate the records you need before buying. Check how you would identify incomplete work and decide what to reteach. Its 30-day trial needs no credit card, giving the school a way to test access before a subscription decision.
Choose this if your school supplies Educake access for your science course or is assessing a school subscription.
Carousel Learning
Best for: remembering topics after lessons have moved on. Carousel Learning focuses on retrieval practice, which means answering from memory before checking your notes. It suits regular recall better than a game chosen only for today's topic.
Teachers can write private question banks or use shared banks. The free Silver plan includes unlimited private banks, three community banks per user and four quizzes a week. Let your teacher choose a set that matches what you have studied.
Treat a missed answer as a prompt for your next revision session. Find the explanation in your course material, then attempt the idea again later. Parents can help by asking about an older topic alongside the current homework, without turning every evening into a test.
Choose this if your teacher wants regular quizzes to bring earlier science knowledge back into use.
Crazy Science Games
Best for: practising a named skill during a short revision break. Crazy Science Games has 46 games for KS3 and GCSE physics, chemistry and biology. Play free with no login, adverts or tracking cookies.
Start from the mistake you want to fix. Try Equation Rearranger for formula practice or Balance It for balancing equations. Cell Builder gives you a biology option. For a different subject or topic, browse the science games collection with your exercise book beside you.
A no-timer round of ten gives you space to think. You can also choose a harder start or class teams mode. BBC Bitesize and Seneca remain the stronger choices for full-course revision; use a game as a warm-up before the main task or between longer study blocks.
Choose this if you already know which small skill needs practice and want a short change of activity.
Build a revision session you can repeat
Choose the course topic first, then decide which site helps you tackle it. Read an explanation or work through course questions before adding a related game. Stop play at the end of a round and write one answer on paper, including your reasoning.
Check our exam board map when matching a game to your course. Teachers can use the classroom notes to fit short rounds around other revision work. If a parent is helping, agree the next task before the game begins so the break has a clear end.
Keep the plan small enough to repeat tomorrow. A note such as "revisit units, then attempt two written calculations" gives your next session a purpose. Choose your site around the task, then start the work.
Which websites should teachers suggest for full GCSE science revision?
BBC Bitesize and Seneca Learning are the first choices here for revision across the science course. Bitesize suits pupils who need explanations; Seneca combines courses with practice questions. Ask pupils to match material to their school course. Add a short game when they can name a particular skill they need to practise.
Can pupils revise GCSE science online for free?
BBC Bitesize provides free revision content and Seneca has free access with limits on content and features. Crazy Science Games is free for every game. Schools considering Educake should budget for paid science access. For home revision, begin with the free course material and review what you need before paying.
How should teachers combine revision websites and science games?
Set a course topic and a written outcome before offering a game. Pupils can read or answer course questions, then practise a related skill in a short round. Ask them to finish with an answer away from the screen. This makes the game part of revision while keeping the wider course in view.
What should parents check before using a school revision website?
Ask which science course the pupil follows and whether school already provides access. Check any teacher instructions for accounts or assigned work. Agree what the pupil will study and how they will show their understanding afterwards. If you are considering homework tracking, ask the school which records it needs and how it uses them.
