    There's only three of you? Whoa! Our school made everyone do medical physics - we didn't even get a choice

    But wow, great! Me too - I can never get my head around whether or not I need to use a negative sign!!!
    Really?? Basically our school made everyone doing turning points as that's the only topic the teachers knew how to teach but also they felt like it was the easiest to pick up as it used stuff from the other units. those who got above a certain ums at AS level got to choose the other options for self study and I chose medical cos I want to be a doctor

    Medical physics is really hard if you're not interested in it! Yeah me either, but never need it again now!!!

    can anybody remember the questions with their corresponding marks? Im not asking for answers or anything, just trying to mentally guess how many marks I got. I did turning points, so if anyone remembers each question n marks for that too, that would be great!

    I would imagine so yeah lol
    wasnt it just asking for the general definition of specific heat capacity though?

    I think it stated the specific heat capacity of Lead and asked what that sentence meant. In which case I believe I'm right in saying you had to explain specifically that 130J of energy would raise the temperature of 1kg of Lead by 1K.

    I got that. It was a recurring decimal (3.0303030303) to two significant figures

    Ah good, this is what i wrote.
    but i added that is it with no change of state, is this correct?

    I'm pretty sure that in Section A the question on the dispersion on alpha particles when using isotopes of gold was 1 mark. The first tick box question was one mark and the 'state the range of alpha and beta' was two marks. The question followed by that about alpha, beta and gamma rays with I believe a concrete wall or something was one mark.

    I know thats not much but thats all I remember so far.

    I somehow got 4 half lives instead of 2. Do you reckon I'd lose all the marks for that question

    I'm paranoid I missed a question in Medical - is this all there was on it? Myopia question, db/dba question, ECG 6-marker and image intensifier?
    there was also a question on incoherent and coherent bundles

    Oh that one was just the thermal energy required to raise the temperature of a substance of 1kg by 1K

    Yeah I added that too, not sure how important it is. I guess it might be one of those awkward underlined sentenced.

    I think it also required use of the "130J" they mentioned.
