    Hey guys,

    Will it be possible for someone to explain Jan 2013, 6b to me? Specifically the C-D part.

    Hello, it is asking you to find the pd between c and d.
    8v for the fixed resistor adjacent to the thermistor.
    And 6v to the top resistor in the midlle. Hence the potential "difference" is 8v - 6v = 2v

    Ahh, that makes a lot of sense. Thank you so much WordPad. I got the right answer, but couldn't quite work out how Your answer's cleared that up. Best of luck if you're sitting the exam

    Please can someone give me a list of all of the possible 6-markers?

    Hey mate,

    Someone on here produced a file for the long answers from June 2010 I think. All credit to whoever collated this.

    I'm not sure about a list of possible 6-markers, but take a look at those answers and try and see where some overlap I guess. Hopefully, it won't be too taxing.

    Brilliant, nice one mate.

    Really worried about this exam. Could go a number of different ways. Hoping for lots on quantum phenomena.

    Cheers! Do you think it's likely that the same question will come up again?

    Not in the same words, but the concepts are pretty repetitive!

    Does anyone know if you get marked down for not performing calculations exactly how the mark scheme wants you to perform a calculation?
    For example if I write out two formulas eg V=(E/Q) and R=(V/I), combine them to form R=(E/IQ) and rearrange for a variable that I want, eg current, to give I=(E/RQ) and then substitute given values for E, R and Q to arrive at an answer. Would I be marked down if the mark scheme said to first work out the voltage from E and Q in one line of working for a mark, and then substitute this into the second equation, then rearrange it to give current for the second mark. Would I lose out on any marks or is it that if the examiner can follow your working and you arrive at the correct answer you get all the available marks?

    I was thinking the same thing. However on some of the papers, when it gives you a circuit and asks you to calculate v, I, R, etc they are always 1mark questions from my experience, and 1 markers obviously don't have marks for method so technically you could do it however you want. As for questions that actually have marks for method, I don't really know. I presume because the basis of your equation was still their main equation then they would have to mark you as correct but I'm not sure.

    As long as your method is correct and clear, you will get the marks. Doesn't matter how you go about it.

    I've come over the isotope definition a million times and I always get the two marks in the mark scheme for saying that "same proton number, different amount of neutrons" but I never know how to word it, I find it weird to write "something with the same proton number....". I hate writing "something" in exams as I've been told by many examiners not to do it. Does anyone know how you could word the definition of an isotope better?
