Yeah i also i think there might be 2 six m

P2: differences between fission and fusion / formation of elements
P3: electromagnetic induction / motor effect

my guesses

Ali think there are going to be 2 six mark Qs on each paper like in biology

Do you think they'll have one of those questions where it asks you why scientists can't advise on matters of opinion?

Nah I wouldn't be able to say- I don't really look at past papers that closely

They always have them, just answer the question using common sense, two to three easy marks

Don't you just draw a line through the top of the lens to the principal focus and straight through the middle of the lens (for a converging lens)?

This is my first post here and I honestly feel hopeless after AQA C2/ C3 paper on 15^th May.
Just want to know what everyone is revising for AQA P2 / P3 exam on 19^th?

All of it..but i think nuclear reactions and life history of a star is likely to come up, and definetly electricity!

You should probably revise all of it just to avoid any regrets.

Really don't want motor effect coming up.

P2 Equation Sheet: AQA-AS1-AS2-PH2-EQUATIONS-SHEET.PDF:

P3 Equation Sheet: AQA-PHYS-W-DS-3.PDF

I mix up my units with every equation it's actually ridiculous.
And you would think it's pretty straight forward...

Use dimensional analysis!

Just check your units on each side of the equation and they should balance up

For example, you know p=mv, so therefore the units of momentum must be the same as the units of mass (kg) times the units of velocity (m/s), so the units of momentum are kgm/s.

How many marks, on average, out of 60 are dedicated to equations?
To me, equations are the easiest marks in all of science GCSE because you get the formulae sheet and as long as you remember the units, you just insert the numbers given.

In my mock (P2) there was literally around 25 marks for JUST equations and I hope this happens again!
