    What about the question that asked you about the advantages/disadvantages of radiation?

    For disadvantages I filled up the whole space with stuff about damaging cell walls, DNA replication and cancer.

    For advantages I said that radiation is detected accurately, so results would be accurate, and there is no need of spending a long time testing - which was random as I just made it up.

    What did everyone else say?

    It was the same question where you had to plot the graph.

    0.8A was from 4V I think...I don't remember exactly.

    wasnt it 'how could a doctor explain the risks and benefits of radiation?' that was weird because its not askin you the actual advantages and disadvanteges, but how the doctor could tell you them. strange question.

    Please tell me it wasn't worth 4 marks..?

    The radiation it asked for how the doctor's would explain it to the patient, I explained it from a doctor's point of view. Explaining the risks of not using the tracer/radiation is much higher than if you do use it, because if you don't recognize you have something wrong with your thyroids it can cause more problems, whereas the chance of having something wrong with the tracer is minimal. The benefits are the fact you'll have peace of mind, and know if you have somethnig wrong. The disadvantages are mutation of cells, if radiation damages cells to cause cancer...

    yeh. i mean, what was all that about. 4 marks for sumthing that doesnt even require physics knowledge. and even so its one of those questions with so many answers that u dnt know whether wat u hav put is right or wrong. a very crap question.

    I don't think it was worth as much as 4, perhaps 2 or 3 marks. Even if you got the answer wrong you'll get your method marks.

    it was one of those (3+1) marks where u get points for grammar i think.

    I think the radiation question was definitely worth 4 marks, I remember thinking 2 advantages and 2 disadvantages.

    The charge question was 2 or 3 marks I think.

    This is bad - now I realise that I've made so many mistakes...

    for that question it wasnt about naming advantages and disadvanteges, but how the doctors explain these disadvantages and advantages

    Yes, it was. I mean, marks for grammar? Physics..? Correlation? I don't think so.. I think questions/mark for punctuation/grammer are strange in a exam like Physics.

    Firestone, you sound like you've done quite well, I don't think you should be worried at all...

    I got 20/20% on my coursework, which is a nice start, BUT my knowledge of Physics is pretty limited... I am predicted an A, doubt I'll get that. If the A boundry is around 65%, I already have 20% of that. Meaning I need 45% of the total mark over two tests.

    this years boundaries should be quite low as i think bio and chem were above the standards of pastpapers ive dun (and ive dun a few!!!) but physics was about on par with the previous papers.

    Exactly, that's what I was thinking. Grammar? I think you're allowed on grammatical/spelling mistake in every sentence. I understand about the scientific language...but grammar? Physics?

    The thing is, the number of mistakes I realise I've made - stuff like how the doctor explains the advantages/disadvantages...

    I think you'll get at least your predicted grade. Physics boundaries aren't usually that high are they...hopefully not, anyway.

    i wrote stuff like how they could show people pictures of effects of radiation in the body, conduct a test in front of them showing effects radiation can have on certain things, telling her about risks and benefits from previous experience etc . jst the sort of things a doctor might do to reassure patients.

    The grade boundries from the other thread... 56 doesn't seem too high to me, I think that's surprising..! My hopes of my predicted grade are rising slowly, but surely
