    Dont think so, that is way too low for 3B paper. Im guessing A will be 30-34 depending on how well everyone did.
    previous to the jan 2013 exam all the boundaries for an A were below 30. I was so surpirised when i saw the grade boundaries for this paper.

    Hey guys just to let u know the answer to the first question is c and the proof is in this diagram which is identical to the one in the paper but without the splits or the labels Attachment 214062
    The answer cannot be d since that is the root cap and the for the second part there are 4 cells undergoing mitosis and there are two marks available so a mark for every two labeled

    Exactly what I did, except that I used a straight line for perflubron and a dotted line for plasma.
    This is the only possible graph I could think of- many of my classmates did the same.
    yes line is correct too!
    but a bar will still compare each at each pressure in the table...do u thnk they ll accept a bar chart?

    but we all made silly mistakes, for me I guess I lost about 12 marks cause I messed the question of put the sketch iunder a paragraph, I choosen 8 not 9.and other silly stuff, hope it will be under 30 not above.and dont forget jan 2013 was a lot easier I think.

    It seems everyone found it easy and did pretty well; does that mean high(er) grade boundaries

    Terrible and great.

    The Bio exam, UGH. So frustrating. I have trembling hands, so the graph prediction question was so hard.

    I hope not ,, most of my classmates-if not all-said that the paper was hard!! So hopefully the grade boundaries won't be high!

    Official markschemes will probably not be out until a week before results day. But If you look at the last page, you find some unofficial markschemes and suggestions to the right answers.
