    Guys I sat for phy p33 today and unconciously I made a blunder . i didnt read the Q2 properly about that angle must be approx 14 and wrote 9° and carried Out my further calculations but my readings for Time were almost similar to others who had done it right.So are there any chances of ECF or how many Marks Would I lose ? Furthermore i think that T was not for a single oscillation because it stated That T is the time gor Number of oscillations You take , so anyone could help me out with those these issues. would Be very grateful.

    I'm sorry but I have no idea...better not to think about it now as tomorrow's a horrible one!
    In physics practicals not as much marks are deducted as we assume

    Dont wrry bro..the readings in practical exams vary from person to person so whether you got 0.5 or 0.7 it doesnt matter unless your practical procedure or working is wrong

    take comfort from the fact that last year i sat for the same paper, made tables and did majority of the paper with a pencil and got an A in practical.

    May i also know.. are cie checkers lenient ? There was a question in p42 " define line of focrce " . I wrote " direction of line gives the direction of force on a mass. " it was asked earlier as well and the ms said " tangent to the line gives direction of force on a mass " . It was of one mark only. Will i be penalised ? I am not too sure whether they are the same :/

    as long as the examiner can understand the answer , its fine but be careful in paper 2 they do penalise.

    Hey,
    dont worry , the practical part of the paper(which depends on your reading) carries hardly 3 marks at max
    they examiners mostly mark on how well you display your readings , so your probably gonna lose like 1 mark for that , and like two marks for accuracy
    Also
    Time period(T) = time for 10 oscillations / 10 (if youvve measured time for 10 oscillations)
    dont try to think too much about this paper , it is over
    the best thing you can do now is to study hard for your remaining papers
    best of luck xx

    theyll award u with ecf i think
    the only mark youll lose will be for the angle u wrote as 9 instead of 14

    Can someone please explain to me, how we find error bars in paper 52?

    error bars = 2 x uncertainty
    draw em around the point

    After reading the comments on the physics practical, I will say this:
    Tables and their workings are fine in pencil. No matter what your gradient and y-intercept are, you will get marks for them as long as you used the correct method and took the right values from the graph(that means taking care of the power of ten on the axes). Absolute uncertainty in angle readings in 2-5 degrees, you may check previous mark schemes, but if you took repeated readings tat uncertainty can be taken as 1 degree(working must be shown for this either in the same part or previous part).
