    Dear Mr M, for Q5 I said compress by a factor of 1/2 parallel to y-axis, how many marks would I get? for Q7 I got x>-1/8, instead of x<-1/8, how many marks would I lose? for Q9ii) I got the points 2 and -5/2 however I may have added up 2 and 2.5 wrong due to stupidity, how many marks would I lose?
    5) drop 1

    7) drop 1

    9ii) drop 1

    Mr. M ... I have got the right answer for, last question but i crossed it out, slightly, but that answer is still visible. I had the right method how many marks would I get? I was unsure, So because i got x=0 and x=-2 so i thought i was wrong.. cross out slightly with the answer still visible, how many marks will i lose.

    There was only 1 midpoint to find?

    Drop 2 marks I expect.
    Sorry, I meant that I got the y - coordiante wrong. Would it still be 2 marks based on ecf?

    Ok thanks. For the decreasing function question, I accidentally did dy/dx = 4x+1
    So I got x < -1/4
    How many marks will I drop?
    Drop 2?

    On the last question I got (1,0) and I put it in and it worked I don't know where I went wrong :/
    i got the same wrong answer haha. I factorized the cubic and noticed there was a repeated root of (X-1), so i came to the conclusion that the line was a tangent to the curve at this point somehow. All i can do no is look back and laugh.

    Drop 1. No-one NEEDS 100 UMS - it isn't that important.

    Mr M, For question 9iii, not too sure what I did but I ended up with co-ordinates (1/4 , 4) any idea how many marks I'll lose?

    Based on what you have told me, zero marks. It is, of course, possible that some of your working was right and should attract some credit.

    does dropping 1 or 2 marks now mean i cant get 100?
    I think the C1 boundary for 100 UMS is always 72/72. You could have gotten away with losing the 1 mark possibly in C2, possibly in M1, M2 and FP1, definitely in S1, C3, C4. (Can't comment on modules outside these 8 yet, sorry.) But not in C1. You'll probably get 95%+ though.

    You know you said you couldn't put up the paper but you could tell us what the question was - well, what was the full last question? Just cause I want another stab at it!

    Thanks!!!

    question 3 i for some reason beyond my imagination treated 6/x^2 as 6x^2 when differentiating, consequently got 12x +2 then 12 for the 2nd derivative. can i claw any marks back for at least differentiating properly, and following through?

    i feel ashamed to be an A2 student and not be able to pick up on such a silly error

    For question 6ii where you have to find B (-2,-10), I know the correct method to find it is via considering the centre of the circle (M) as the mid point and working from that (A + B)/2 = M.
    But how many marks would I lose (if any) for solving it by considering they are directly opposite in a straight line and they are an equal distance from M so getting from A to M is the same as going from M to B so adding that difference to M. i.e. (2,2) to (0,-4) is going -2 in x and -6 in y therefore A is at (0-2,-4-6) = (-2,-10). Will this lose me a working mark, in your opinion?

    Thanks for the answers btw
    That reasoning is fine.

    And you are welcome.

    4iii) Calculate the discriminant of 3x^2 + 9x + 10

    7i) Solve 3 - 8x > 4
    that's brilliant, thanks, by the looks of things I've done extremely well

    Haven't I answered this already? You are not giving me enough information to go on. If you just wrote that wrong coordinate you won't get any credit.

    Mr M i know its a lot to ask, but what do you reckon realistically the grade boundaries are, compared to past papers (assuming you've done them before :P)

    For the very last part, i correctly calculated x=0 and x=-2, showing all my working. I then had no idea, so I then guessed and put x=-2 y=-27 underneath. I wrote that down but didn't put any working and didn't obviously exclude x=0. Will I get all the marks?
    Thanks for the answers!
    You might get full marks if you are lucky!

    And you are welcome.
