    Arghh. Im screwed
    Messed up the hear questions so bad! Plus for the vaccine questions, i didnt realise that the memory cell would recognise the protein in the heart muscle as its antibodies complemantary antigen. Imstead I worte on re-infection of clamidiyia the antibodies would attack. Basically was against the vaccine cos reinfection of clamidiyia would lead to antibodies attacking heart. Didnt realise that the memory cells would do that anyway!!!!

    Also, For an A*, I know you need 80% in AS modules and 90 % in A2 modules. Is that 80/90 % of raw marks or UMS?
    UMS

    UMS not raw marks. Usually around 70ish% in raw marks converts to 80 UMS

    hey........

    failed........... urgh...
    Dont worry too much, application questions are a killer. The most suprising this was the fact that the last question was 6 marks wtf?!?!?!

    I'm hoping the grade boundaries are low because of the change in layout and the tricky questions, but then again this is a June series exam where all the geniuses come out to play :/

    Alot of students retake, but don't forget there are still loads of school who don't take January exams, so the grade boundaries could come down if everyone was caught off guard, like seriously the last question 4/6 marks? I was like :eek: its always been 5/5!

    It was 1.4 I think.

    Just rearrange the equation: Pulmonary Ventilation = Tidal Volume X Breathing Rate

    I did difference in pressure between at 1 second and 3 seconds. Divide that by 3 and i got 1.4 . Dunno if thats right or wrong

    Yep. I think it depends on if you divided it by three or four. I tried both and decided 1.4 seemed better. I think. I remeber getting 1.17 somehow and thinking it was too low.

    What other points would you have made for that?

    Also, none of that, got 100, wrong. fml feel like dying.
    I talked about:
    Villi having a large SA and so increasing the rate of absorption

    Micro Villi further increasing this SA

    Carrier proteins, protein channels and active transport and facilitated diffusion also aid the flow

    Movement of blood maintains the diffusion gradient

    The movement of the villi so that glucose-rich food is available - maintaining the diffusion gradient

    Not sure what else

    Bet I didn't read the question again then. D:
    I did from 0-3. Didn't it ask for that? Did 3.5/3.

    Not a bad paper ... For heart rate I got 86bpm. Everything was alright, apart from the vaccination question which baffed me for a bit.

    However, for absorption question, I mentioned microvilli for SA, thin for diffusion pathway, moving and all. But seeing as it was 6 marks I started mentioning mitochondria for ATP and active transport. Then I got a little carried away and wrote about the endoplasmic, golgi, and all that. Reckon they'll mark me down?

    Also, guys, don't stress now. What's done is done - Focus on your other exams!

    I think it was 1.4

    It was 4.2 for 3 secs
    so, for 1 sec 4.2/3 = 1.4
