    Hey what did people put as the % increase? I am not sure if it was 62% or 55.55%?
    It was like 55.5555555, so I guess 55.6 or 55.56 is best .

    I said because the other infections may kill people so hard to see if it was just MRSA?

    Think I went for something along those lines, it said in the paragraph it may kill people who are seriously ill. So figured alot of the deaths could of just been down to the other serious illnesses, hard to tell .

    Found the 1 marker questions the hardest to actually answer in the paper >.<

    1 markers are always the hardest.
    Such as why synthetic EPO (or whatever) increased blood pressure?!

    The question was about how its hard to identify its MRSA-so i said it could be a disease that is also resistant to methicillin but isnt MRSA.

    And i found the 1 mark q's quite odd as well. I don't think i got the "why is it better to use 10 leaves when dealing with micrograms" one.

    WHO KNOWS..
    That is why we cannot make an unofficial markscheme with AQA.

    I just guessed that was because it increases RBC production, more stuff in the same amount of space inevitably = higher pressure .

    Only question on paper I couldn't be bothered to think through was why they used unit per mass and unit per time or something. Had lost the will to think through these crappy questions by then and just wrote some dribble :P.

    yeah it was 3, I didn't mention diffusion but osmosis instead?
    yes osmosis is correct, i didnt mention hydrostatic pressure but mentioned ozmosis and lymphatic system, hopefully that will get me 3 marks

    It would of been fine if it just said use 10 leaves, I didn't really get the relevance of the measurement though. I just said increases reliability, being able to use a mean etc :|.
