For Q5c did it not ask for root mean square speed? In which case you would raise to the power of 1/2


Nope just the mean square speed

Also I'm still unsure as to what the mark scheme will allow for the maximum range of beta in air, different sources state different values. I learnt it as 5m :L
Does anyone who did the applied one want to check answers with me? Thank you.
Would 60/75 be 120 ums? Thanks for any opinions :smile:

I don't think so. I reckon it'd JUST be an A*

it's very hard to judge but if the grade boundaries wont shift by more than 2 marks, and that you're sure enough with your marks then yeah that would minimum be a B

Are there any mark schemes for unit 4 and unit 5 section A and medical physics. Have a feeling I got 55/75 in unit 4 and 63/75 in unit 5, and I know I got 49/50 in practical. Will that be enough for an A*?

Let us hope that we can get the mark schemes before the results day so that we could ask for the review of the script of the papers if we think the awarded grade is not fair. I know that the examiners cannot read my answers to the six markers lol

Revised mark schemes (some of the mark allocations/question numbers were incorrect)
