Frequently asked questions
Is this the right Topic P8: Global challenges page for my course?
These notes are for GCSE OCR Higher Physics. If you are on a different exam board or tier, choose your course from the Physics page instead, because the content is not always the same.
What should I do after reading the lessons?
Test yourself without the notes open, then try past-paper questions on the same topic. The questions you get wrong tell you which lesson to go back to.
