    My guess:

    100 UMS = 81/90
    90 UMS = 74/90
    A = 67/90

    Tougher than last year by a long way, but by no means the toughest ever.

    Guys what did you do for the last 4 marker on the comp about percentages.

    Since it said 'about right' I just classed the 70 and 80 together then went on through there.
    Yeah I did the same but I think I've got them the wrong way round, would a larger focal length preference mean that they would think it would be too small?

    All correct.
    I got 90-56 for the angle. I worked out the angle between AG and the perpendicular to the plane and took away 90.

    Maybe 71 for an A?
    You mean an A*?

    june 11: 70
    jan 11: 80
    ect.... so an average paper has a boundary of roughly 76/90.

    what do people think about the relative difficulty of this paper ? i think the parametric equation question alone is going to bring down the boundaries a bit. i would guess a boundary of maybe 75 ?

    Yeah I agree and maybe the second part of the stacked triangles question. Tbh I thought the comprehension was harder than usual

    <70Focal length found it to small
    70-80 found it just right
    >70 Focal length found it too largr

    Wouldnt it be <70 found it too large?
    and >80 found it too small?
    The larger the focal length, the smaller the field of view and thus images appear larger.
    So for those above 80mm will prefer a larger image and will therefore think it looks too small, whilst those beneath 70 will be used to a larger field of view, so 75mm will look too large?

    I think it's the other way round cause the larger the focal lens the smaller you observe it to be

    Yeah that's what I think! I originally put the other when in a rush but then changed it as those preferring larger focal lengths will find it too small!

    Yeah, that must have been what we both meant. I went over the logic a good 10 times in the exam, so I'd be surprised if I got it wrong
