    also what did you put for the penultimate question - a reason why the portal vein's blood sugar concentration had changed - wasn't this basically what the last question was asking?

    I hope that they say allow artery because i'm pretty sure the CGP book follows the specification. If not I don't really care it's only 1 mark and I only need a B.
    The bit about stents talks about the coronary artery.

    I've never been so relieved that nothing about biogas generators came up

    I thought the 6 mark question was gonna be on it. But there was nothing really on biogas, deforestation, global warming, Mycoprotein or fish stocks.

    Im so relieved that the exam was easy because I hardly revised for this exam!

    My prediction is similar to Captain Anonymous but I would say A* would be 47.

    i thought the exam was good , a few tough questions... I think that i got somewhere between 47-50.
    Where do you think you lost marks?

    I think I'm just going to lose marks at questions where the mark scheme is a bit picky but I'm hoping for around 50.

    Do u think saying modern ventilators are more reliable would get you a mark.

    And for the one before, does saying that iron lung decreases pressure whereas modern ventilator increases pressure, get you the marks?

    Definetely. Some questions later on, although you may have got the answer right, the mark scheme I feel will be a bit picky and so you could expect to lose marks there.

    I'm not sure what would be on the mark scheme for that question but I have a feeling the key words will be negative pressure and positive pressure as they never mentioned this in the explanation bit. Wait till Nightstrider and Captain Anonymous get home and I'm sure between them they will have a good guess.

    I knew what they were, just couldn't spell them. Hopefully the examiner knows what I mean.
