    :eek: omg i'm so sorry you missed them, i don't mean to be one of those annoying people who try to make you feel better, but if you did well the rest of the paper then it shouldn't have much of an effect on the actual grade
    Haha I'm sure it should be fine overall, I was checking through it for 10 mins and still didn't see the 'question 4 continues on the next page':mad:

    Nope, only saw them as the woman was collecting papers, how many marks was it?
    It was 3-4 marks. Just hope you've done enough for the other pages.

    Haha that was lucky, the annoying thing is they had a blank page after question 1, why not bring it all 1 page forwards and avoid the confusion?!

    Yeah from what I've looked up in the revision guide/book I can only find about 2 or 3 other marks I've dropped, so should be fine (although may Cambridge hopes have been diminished)

    That's just a rounding thing, should still gain you full marks to that question since it still remains close to the other answer

    I got 56.9 right at the end. Only at the end I realised you're supposed to calculate moles of magnesium carbonate to get the moles of CO2, then just times moles by 24,000cm3 to get the answer. I messed up first, but then writ at the end I got the correct answer. Would I get full marks or not since my working out was messy, but my final answer was clear, and it does usually say award full marks for a correct answer?

    Thanks

    I think it shouldn't matter about how messy your working was as long as some method could be seen. If the answer was right you should most likely get all the marks.

    Lol then they talk about CO2, but what about all CO2 caused by these exam boards in wasting trees and paper. Someone should write on the blank page
    What a bloody waste o trees and paper. This causes greater CO2 levels. Hence greenhouse effect occur.......

    Hahah
