Post your working. An examiner marks it.

I'm Rich. I'm Cambridge-trained, I marked IGCSE Physics (0625) and A Level Physics (9702), and I've read every examiner report Cambridge published for both syllabuses from 2021 to 2026.

Most answers lose the mark somewhere other than where the student thinks. That's the gap this room closes — and it's the one thing a mark scheme on its own can't tell you, because a mark scheme can't see what you actually wrote.

The Physics Help Desk

Post a question with your working and you'll get an examiner's read on it: where the marks actually are, and why one wording earns the mark when another that means the same thing earns nothing.

Free, and it stays free. No card, nothing that expires.

What actually happens in there

01
You post your working A photo of your page is fine. Say which syllabus and paper you're on, and put it in the category for it — the room is split into IGCSE 0625 and A Level 9702 so answers stay findable later.
02
I mark it the way I'd mark it in the exam Not "here's the right answer". Where your marks were won and lost, which line the accuracy mark turned on, and what the mark scheme would and wouldn't accept from the wording you used.
03
Once a month, I mark a real past paper question live A full question, worked in front of you, with the examiner report and the mark scheme open. Recorded and left up, so it's still there if the timing doesn't suit you.
04
Everything stays up Someone else's marked question is worth reading even when it isn't yours. Most of what students lose marks to is the same handful of habits.

Two rules

  1. Show what you tried. I'll always answer that first, and a question with no working is one I can only guess at.
  2. Never post live or leaked exam material. Past papers and mark schemes only.
Mark scheme detail is 0625 and 9702, because that's the corpus I've read end to end. The technique transfers to any board — post anyway and I'll flag what's Cambridge-specific.

Free trainers, while you're here

None of these need a login, and none of them are behind the room.

Questions

Is it really free?

Yes. The room is free and it stays free. There's no trial that expires and no card to enter. I'm also opening a separate paid room for A Level 9702 students who want live teaching every week, but nothing in the free room is a preview of it.

I'm not sitting a Cambridge exam. Can I still join?

Yes. The mark scheme detail I quote is 0625 and 9702, because that's the corpus I've read end to end. The technique transfers to any board, so post anyway and I'll flag anything that's Cambridge-specific.

What do I have to post?

Your working, not just the question. Most answers lose the mark somewhere other than where the student thinks, and I can't show you where unless I can see what you wrote. A photo of your page is fine.

Do I need an account somewhere else?

The room runs on Skool, so you make a free Skool account to post. The trainers on this site need no login at all.

Ready when you are

Bring the question you're stuck on

Bring the one you've already got wrong twice. That's the one worth marking.
