    I agree, some teachers are absolute tools. Too true.

    HAHAHAHA :D

    Why are you all blaming your teachers , you know what they say a bad work man always blames his tools :L
    a)Good Teacher + Good student = Deserved results

    b)Good teacher + Lazy student = Bad results

    c)Bad teacher + Good student = Disappointing results

    Most of my teachers are C but some are A :).

    If you had my teacher you would not be as quick to criticise...

    Yeah he properly goes to one of the poshest schools in Ireland or something and thinks that all Irish teachers are amazing :P

    what was the one about the graph on salt? There was no figures on it so I didnt know what to say?

    doing past papers without notes i managed to just scrape an a but that exam was (hopefully) a b.
    everyone in my year was pretty disappointed though so

    It was 40 g or something, it was hidden at the end of the paragraph at the top, which I didnt read:rolleyes:

    You only need 510 marks so if you get full in course b and then you can afford to lose 80 marks :)

    On iPod, not trying to quote.

    That was a horrible paper, science is one of my favourite subjects and I found a lot of other papers grand but the one of the topics on this suited me!

    That question about the environment was terrible.

    Biology really threw me off at first - human reproduction which I'd completely forgotten was on the course!

    Took me a while to find the salt, it was in the question.

    I was delighted when the equation I learned came up!

    Does anyone else think the SEC made a mistake with the electricity graph? Doesn't it violate Ohm's Law because it's not directly proportional?

    it was the 2 that were off were due to experimental error.... and i wrote the damn wrong equation didn't read it fully..... i knew them soooooo well I can still recite them... I believe my coursework was amazing i halved all the lines and still filled up the extra space halved and i went in great detail and spend ages on my diagram. Never been so proud in my life... Im really hoping for that a since im doing 4 sciences next year

    Hi,
    I was wondering do they ever reduce the marking scheme for science because that science experiment, everyone got caught in that 18 marks !!!
    That could be my difference between A and B

    It wasnt really a mistake because you would not get exactly a straight line increase there might be +/-0.1 if you did the experiment on the Ohms law . Ithink the answer was meant to be 1 ohm cos if you roud off the rest of the figures you should be fine

    0.4v/0.4i = 1ohms

    You were meant to take figures from the table, not the line.

    With the Ohms question, they allow a range between 0.90 - 1.10. If you got between them two figures, then you get the marks. The graph should be a straight line ... because the current is directly proportional to the voltage supplied, so it has to be straight. :)

    Mine was slightly off being straight :O Damn it, I should of remembered that from the experiment we did xD

    Was the line for the salt a straight line along the 40 x-axis?

    My line was off for the ohms (If I am thinking of the right one) because of their figures. It's not up to me to fix that.
