Haven't seen a G482 thread here and since I saw a G481 only just go up a couple of days ago, I thought I'd make one for G482

How is everyone preparing?

You need to work out how many electrons will be emitted per second - then use that to get the charge per second.

LOL please tell me someone made predictions for tomorrow's exams 😭 I'm sooooo dead for tomorrow!! I hope they don't ask hard question
I hate potential divider questions... I hope it doesn't come up

Considering last years paper was excellent for most people. This year is likely to be difficult. Read the examiners report. Since the first 3 questions from last year was Electricity there wont be much on it i think. Loads on the other stuff i guess.

Oh no... I hated that paper.. I really hope that it's not difficult.. I thought last year was hard because people complained about it???

Also what mark do you need to get out of a 100 to get full UMS???

You need 100/100 to get full 150 UMS

Just a list of prediction I think will come up based on from last years paper:
Longitudinal Transverse Waves
EM spectrum
Diffraction
Loads on Quantum Physics except photoelectric effect
They basically asked a lot on electricity so i have no idea what to expect.

Depends on each paper last year to get full UMS was 78/100. On physics and maths tutor they have the 100ums mark for each paper

How did everyone find it..
I found it hard tbh... but it was sort of better than last year but still... I didn't understand the electro acceleration question

Is anyone going to make the unofficial mark scheme for this paper

Would you be able to make the unofficial mark scheme please? I know you did it last year and it helped if you don't mind of course lol
