    Depends on the grade boundaires. Maximum you can get is 140 UMS. It is out of a 100 marks.

    So 80/140 * 100 = 58/100
    120/140*100 = 86/100
    It totally doesn't work that way.

    It converts your mark for whatever paper you did into the UMS

    Its pretty simple. You can see that there are two strands from the graph.

    One is 64 and the other is 36.

    So you want to find two places where when the cuts are made , you'll end of with them strands.

    When the L and M cuts are made. You get a 36 strand so the other must me 64 as the total is a hundred. So these two restriction sites are cut.
    Yes I get that! But the data on the graph didn't really seem to go

    Hey I just got a few questions about this paper, and apologize if they've already been asked/answered just don't fancy reading through alot of pages to try and find them :3

    • What are predictions out of 100 for A/A* boundaries?
    • I got 95 UMS in unit 4, so do I just need 85 UMS in unit 5 for A* or still require 90+?
    • Are the answers for specimen paper question 5 a) (i) and (ii) both wrong? As in shouldn't it be Na+ moves into the axon, and K+ moves out?

    Thanks in advance

    I don't know about the grade boundaries but the specimen paper mark scheme is wrong on that question.. actually it's a pretty dodgy mark scheme overall.

    you need to get an A overall 480/600 i think.. then out of the 480+ marks you've got, 270 of them need to be from A2 units, so unit4, unit5 and unit6. hope that makes sense!
    also, i think the spec paper answers are wrong too! Na+ moves in and K+ moves out.

    Describe the sequence of events leading to the release of acetylcholine and its binding to the postsynaptic membrane.
    Action potential arrives,and calcium ions enter the synaptic knob. The vesicles fuse with the membrane and acetylcholine diffuses across the synaptic cleft. Then it binds to the receptors.

    Is this right? :confused:

    pretty much, depending on the amount of marks more detail could be added
