    K.. lol yeah it was good but you can't really say youve definately got an A. kthanksbye :P
    apart from the one about more red blood cells, i think i got everything else right, remember the grade boundaries are usually 65% for an A, i got well over that by counting the marks ( potential marks ) , how did it go for you ?

    I hope so, I thought it was harder than Jan 11 though, and I need 121 UMS for an A overall. I felt fine until I came on TSR >.> I hope we both did okay!
    How do you know how much you need? Do you know what the ISA grade boundary was? :afraid:

    I hope we did m8!

    I really dislike biology now. And the worst thing is, is that I was fairly confident that this exam would be ok. Oh how misguided was I.
    Hehe, me too.
    I remember last night I was imagining what it would feel like to get full marks...

    ...well I needn't have bothered, it isn't happening any time soon.

    The red blood cells was good.
    I think i messed up on one calculation, the frog question, erm, the DNA base thing cause i didnt realise there were two strands.. woops..
    But hopefully i can still get an A? \:

    why did epo decrease blood pressure?
    because the increase in red blood cells increases the volume of blood so this increases the blood pressure?

    I put that the pesticide would mistake the small egg for a pest... and I genuinely thought that it made sense at the time.

    I also thought that the DNA base pairing thing added up to 100, and pretty much realised my mistake when we got told to put our pens down. My brain melted.
    Don't worry, I put something even more stupid - because the eggs are small, they will be large in number (:lolwut:) so they will get killed. And also, pests are small, and guess what? So are the goddamn eggs! :facepalm2:

    My brain melted as well.

    Using last years ISA boundaries, I need 121 76 in bio1, 43 in ISA, 240/300 for an A D:
