    I haven't been able to find one so I thought i'd make a thread on this exam!

    22 DAYS FROM NOW is the WJEC PH2 EXAM.

    How's everyone feeling? Are you well into revision and how do you find it in comparison with PH1?

    I do it

    I'm feeling very bad about this exam, it's going to be the one that will let me down. I just did a paper and got 55% lol, but anything over 50% in physics is good for me.

    What about you?

    Yeah wasn't too bad. There were a few tricky questions.

    I reckon the grade boundary will be around the 60/62 region for an A. Any thoughts?

    I'm not too sure seems reasonable, but a lot of people from my school really struggled with it.

    ran out of time, didn't touch the last two questions

    Felt sure I could have done those if I wasn't so slow! I am officially "slow processing" and they give me extra time, and it still wasn't enough!

    I did lotsa practice papers over the past few days, plus hours upon hours of going through definitions and exampls and stuff, and I kinda feel like Will from the inbetweeners - I worked so hard and it hasn't paid off. Though at least I didn't **** myself.

    I thought it was a relatively easy paper, as I said I could have done those quesions given more time. what are the boundaries usually? 62 seems pretty low.
    Didn't get any chance to talk about it IRL

    PH2 boundaries are usually between 54 and 61, depending on the difficulty of the paper.

    That was dreadful, I'm sure I've lost over 20 marks - mainly through rubbish explanations. I didn't like the mean days question and I even messed up on the frequency in the first question!
    It feels down-heartening when you say the grade boundaries will be in the region of 60-62 haha

    Its only an estimation

    The response after the exam from my classmates was very varied, so the actual boundary might not even be close to that.

    There was lots of scope for ecf in this exam so I don't think there's much need to worry about losing loads of marks for one little mistake, or such.

    I wrote pumping initially, but then saw that the next question was about pumping - so I thought hmm.... Excitation? Then I wrote about that xD
    As for the particle, if I recall correctly it was an Anti-electron Neutrino, might be wrong though.

    The pi+ decays into a positron and neutrino, the pi- into an electron and antineutrino.
