    Hi. Please don't worry - my mum is an invigilator and she says that the most important thing to put on your paper/papers is your candidate number followed by your name and centre number. If you didn't write the number of booklets used then that's ok. The scripts are immediately bagged up in candidate order and sent off to the examiner. Any loose sheets/booklets which have come away from the main paper will be slotted back into the main paper so its very very rare for any to go missing and you certainly won't be marked down for not filling in this detail. Hope that helps. Good luck with the rest of your exams.
    Thank you so much!

    Can anyone explain why a graph of P against 1/v goes through the origin?
    1/v cannot be 0

    Right so the first term:
    \frac{1}{2t}-\frac{t^{2}}{2t}\Rightarrow\frac  {1}{2}\left(\frac{1}{t}-t\right)

    Second term:

    \frac{2t^{3}}{2t}-\frac{2t^{5}}{2t}\Rightarrow t^{2}-t^{4}\Rightarrow t^{2}\left(1-t^2\right)

    Third term:

    \frac{6t}{2t}-\frac{6t^{3}}{2t}\Rightarrow 3-3t^{2}\Rightarrow3\left(1-t^{2}\right)

    I'm doing standard OCR Chem, so my course is a little different to yours, but knowing the chemical equation and the rate of formation of iodine, could you not work from there?
    Err could you explain how I would use those 2 things? Sorry Im really stupid haha

    There are probably some assumptions that we use in our gas model which allows it to go through the origin as a result of extrapolation. Try having a gas in 0 volume in the first place... It's like a potential graph of the Earth and distance from centre - what are the gravitational forces like within the core? Very complicated stuff.

    Why?
    Well pressure and vol are inversely proportional

    So if you plot pressure against reciprocal it just has to be linear through origin

    When you do pv you see it's asymptotic

    Any tips on forgetting an exam you just sat even if you did very good?

    I did very good in my last 2 exams but I have 8 more exams. I can't stop thinking about what ums I scored in the 2 recent tests.
    Does anyone else feel obsessed to know what mark they got after an exam? What do you do to forget about it?

    It's fairly normal to think about an exam after you've finished it but dwelling on it for too long definitely isn't healthy. There's no way you can know your mark before results day anyway so no point in obsessing over it. Just start revising and focus on your next exams.

    We all did 32?
    I dropped marks so stupidly
    I couldn't do the ii part of the integration question (3 marks) - I left it to the end and ran out of time
    And I dropped at least 1 mark for the complex roots question (as I had to use my calculator at one point).
    I did get the differential equation after 2 tries haha
    So I reckon I got 70/75 or so.
    I got to do the vector one. Do you remember what equation you got for that one? I only remember d was something like 15 or 19, and that a or b or c where 7, 1 and 4 in some order and with negative signs in one of them. (or something like that!)
    I've lost 10 marks
    (Original post by binarythoughts)
    So did I! Didn't like the differential question but the rest was okay
    I loved the differential question!

    Providing you haven't plagiarised anything, you don't need to worry. Also, if, by any chance, you got a lower grade than last year, then your higher grade would stand i.e. the B from last year so please don't worry. Hope that helps.

    i looked at a students piece of work from years ago which isnt on the web or anything, so an examiner wouldnt be like 'oh this reads similar to timmys from 2009s piece i wonder if she saw it', i reckon its the teachers trying to scare me as they have to cover their own backs as they would be disciplined etc?
