Questions

Which exam boards does GCSE Combined and Separate Science cover?

It follows AQA, Pearson Edexcel and OCR Gateway, Combined Science and the separate sciences. Choose your board above and each unit shows its specification reference for that board. Higher-only lessons are marked, and choosing Foundation above hides the topics that are Higher only.

Is it for Combined Science or the separate sciences?

Both. Every unit covers Combined Science, and the lessons that are only for Biology, Chemistry or Physics as separate GCSEs are marked. Choose Combined above to hide the units that are separate-science only.

What is free?

74 of the 180 lessons are free, with exam-style questions marked as you go. Brainlag Plus opens the rest of the lessons, the topic tests and the mock papers.

Do I need an account?

No. Your progress is saved in this browser. Sign in to keep it on your phone and your computer, and your exam board and tier stay with your account.

How long does it take?

About 67 hr of lessons in 31 units. Each lesson takes 15 to 25 minutes, so one fits between other things.
