    1 markers are always the hardest.
    Such as why synthetic EPO (or whatever) increased blood pressure?!
    I could be wrong here, but i said it adds more red blood cells to the blood, which increases volume, which increases pressure. Only thing that made sense to me-not entirely sure if its right though...

    The high blood pressure was one mark, I think more red blood cells would suffice.

    according to the AQA website for the new specification the Biol2 is out of 85 and to get an A you need 52 which works out 61% which seems crazy low

    Would appreciate it if someone could confirm/correct me on this

    that was for the jan 2011 paper...they mark the papers first and then decide the grade boundaries based on everybodies performance

    I don't think the row should of been the same, if you got 11 for A on the top row, I think you should of got 11 for T on the bottom row. (As they were 2 strands of the same DNA, so should match up with each other).

    I got like 26 19 9 20 as they all add to 148 (the 74 base pairs).

    - yeah basically resistant strains survive, reproduce pass on plasmid containing resistant allele to next generation via vertical gene transmission. as the q was about trouble of antibiotics i also added horizontal gene transmission and how this leads to 'super bugs'

    It changes each year of course, I'd *guess* (from no knowledge of past grade boundaries) around 70% would get an A? Biology is always notoriously low. Unit 4 especially is sometimes UNDER 50% for an A.

    it's only low because AQA are so bloody vague!

    - so what is the grade boundary for 'A' and 'B' do you know? I got a C last year and revised a fair amount this year and doesnt seem to have paid off
    Ah, that 65% is just a general guess, going by the boundaries from the last few papers...
    From the last 4 sessions, they've been:

    Jan '11: A(64%) B(56%) C(45%)
    Jun '10: A(69%) B(61%) C(53%)
    Jan '10: A(61%) B(54%) C(48%)
    Jun '09: A(65%) B(58%) C(51%)

    Yeah it's hard to find the marks especially in unit 4, and they're always like 50% hsw so not many topics even come up >_<.
