    Wonder if first question threw anyone with it being RNA instead of DNA.
    The 2 fragments were Phosphate and Ribose, but alot of people I know just put sugar, wonder if they'll accept it
    Ribose!!!
    :facepalm:
    I put sugar

    I loved this exam! what a broad essay title! and the questions were very related to the spec and past papers. it was a beaut
    I wasn't expecting so much synoptic stuff in the actual questions and there to be almost nothing on responses and action potentials!

    found this solid
    I cant believe it in comparison to june 2010, which i thought was a fairly decent paper I thought this one was horrible!!
    I just pray grade boundarise are super low - no one has said it was easy
    IN june 2010 the grade boundaries were as follows:
    A*- 69
    A - 62
    B - 55
    C - 49
    D - 43
    E - 37

    This year I reckon
    A* - 64
    A - 57
    B - 50
    C- 44
    D - 38
    E - 32
    anyone agree?? too harsh?? to nice ????? xxx
    People seem to have found the paper itself harder than last year, but the essay easier. The essay is a biggg chunk of it really. I wouldn't be surprised to see it about the same. Could be wrong though

    Anyone else find the exam harder than June 10?
    I dont even think they should be compared - completely different league!! June 2010 was alot off application, this paper was full of graphs and hsw!! grrrrrrrrr what do you think grade boundaries are gonna be like??

    I didn't try any of the maths ones, thats about 5 marks down the drain. Missed out about 5 questions, 20 marks down the drain.

    Ill just have to hope the few i answered were right.

    I need an A in this exam, if grade boundaries are as low as they were last year, im in with a small shout, otherwie, goodbye uni

    loved the cycles essay! i predicted it would come up and did practice essay on it before hand (i think im psychic)
    also it was 80 0 0 for the % question cus it was only asking about nervous stimulation and at 1 it was 8 units whilst at 1 hormones was 2 units.. therefore 80%! at 2 and 3 hours nervous stimulation didnt affect it at all!
    and 5:1 for ratio i think is right too! messed up all the pupa questions or whatever they were :P

    Question 2: What does "very large" represent?

    Answer????/
    Lol seemed such a stupid question I didn't really know what it was asking for. I just said something like "The rest of the plasmid and unknown DNA"

    I hated question 9 :/ missed 3 2 mark questions out cos I was rushed for time to complete the essay, so I didn't complete the paper. Found it harder than June but that's partly because there was so much DNA technology in there. I spent ages revising nerve impulses and muscle contraction but there were no questions on it. I wish I spent half as much time on DNA tech than I did for nerve impulses and muscle contraction :mad:

    Thought the essay was brilliant - did the use of DNA question. The other questions were difficult, but I hope I've done enough for a B/C.

    My tactic was to do the essay first, to get that out of the way. Ended up answering all of them bar one 1 marker.

    Cut it twice? :P

    O whole
    (_) one cut
    ( ) 2 cuts?

    So yeah it showed the plasmid would be cut once leaving (_) so if 2 fragments were produced, the unknown DNA must have contained the recognition sequence for the restriction enzyme to cut again, hence ( ) formed.

    Yeah but the question said it was cut once?
    Im confused

    Tell me you put 2 in the answer for number of cuts or something

    Did nobody do the DNA essay? i thought that was a beaut! made up for the stupid questions on this essay that hardly related to this unit!
    I did and alomst everyone I know. I got a bit confused on the whole 'use' part though, did it want you to explain how the process worked or how the process could be applied or both?

    What a weird, weird paper.

    What was the point of learning so much, when really they weren't going to test us on any of it...
