Anyone know how the topics are split up between the two papers?
Or is it just random/all on both?

Random, I think.

Honestly I'm feeling ready for paper 1. Just path difference gets me and specific charge for some reason XD I understand it but always calculate it wrong because I put brackets in wrong places XD Advise wise remember to always look for conversions because they trip up a lot of people. Also write down everything the question gives you inc what it is and units e.g mass-5kg then figure out the formulas you need to use based on what you have and what you need.

The topics are split between the two papers but paper 2 has multiple choice and practical type questions. Also what is on paper one will not appear on paper two. So once paper 1 is done revise all the topics that were not assessed on it for paper two.

No. I still cannot do mechanics or uncertainties

Here are some flashcards on uncertainties and other practical skills

Really? I was under the impression that even if a topic appears in Paper 1, it can very well still appear on Paper 2. :confused:

Thats not on the spec.

Derivation of diffraction rating formula is though.

How do you know what the uncertainty of a value is. For example if it’s 3.20 mV what is it’s absolute uncertainty?

Do you have the 2017 papers on you? If you do do you mind sending me a copy so I can practice? That'd be really great.

How do you know what the uncertainty of a value is. For example if it’s 3.20 mV what is it’s absolute uncertainty?

your measurement=(3.20mV)
your absolute uncertainty (of equipment)= +- 0.01mV (as it is giving a value to a precision of 2d.p)
% uncertainty= (absolute uncertainty/ your measurement) x 100
> (+-0.01/3.20) x 100= 0.3125
but since the absolute uncertainty has a precision of 2d.p the % uncertainty will also be to 2d.p of 0.31
>% uncertainty= 0.31
