Stuck on a physics question? Post it here.
I am Rich, a Cambridge trained physics examiner. I marked IGCSE Physics (0625) and A Level Physics (9702), and I have read every examiner report Cambridge published for both from 2021 to 2026.
Post a question with your working and I will tell you where the marks are, not just what the answer is. There is a free six lesson maths course in the Classroom, and one open live session a month.
Technique here works for any exam board. Mark scheme detail is Cambridge 0625 and 9702, because those are the two I was trained to mark.
What I want this to become: not me answering one question at a time, but a group going through the same year who help each other, with someone in the room to add the exam specific part. So answer each other. I will correct anything that needs it.
Rules are short. Post what you tried, and say which board and paper. No live exam material. Be decent, everyone here is stuck on something.
This room is free and it stays free.
