1. Is there an unofficial markscheme anywhere?
2. If that was c1 then i'm ****ed for fp1
4. How many marks was the whole of question 7
5. (Original post by voltz)
I think i put -41/4
y=(x-7/2)-41/4 to y=(x-4)
so to get rid of the -41/4 you need -41/4 on LHS
vector [a,b] for y=x is y-b=x-a so must be positive in vector to be negative on LHS of equation.
Sorry, bit of a confusing explanation; don't know how else to word it.

CT was 9 not 4 (AT was 4) - see image attached (√65^2 + 4^2 = 81. √81 = 9)

var ctx = document.getElementById("canvas".getContext("2d"; // #text4142-2-6 ctx.lineJoin = 'miter'; ctx.lineCap = 'butt'; ctx.lineWidth = 1.000000; ctx.fillStyle = 'rgb(0, 0, 0)'; ctx.font = "normal normal 40px sans-serif"; ctx.fillText("9", -2.519531, 29.687500);
Sorry - meant that. Got got C and A mixed up.
7. (Original post by timtjtim)
No, sorry. It was 81/4 - 9 (triangle) which = 45/4 or 11.25
hey i messed up some how on the last step of finding equation of P ( used the right method) meaning i got point Q wrong and so forth couldnt work out the area! but i got the correct integral and the correct method throughout and so how many marks will i loose for this whole section??
8. does 2 plus or minus root 10 ring a bell for anyone
9. Its +41/4 as it was already a negative translation, you had to increase it by 41/4 to get to 0, so its positive in the translation vector even though you write y-41/4 in the sum

I got -1 plus or minus root5 if we're talking about the same question
11. Anyone know when there will be an unofficial mark scheme out?

Ooh, I got -1 +- √5 for one... not sure about 2+- √10 tho.

ye thats the only question i wasn't to sure on

Think I got k<-3/2 and k>6
I got the same

AH, I forgot it was FROM (x-7/2)-41/4 to y=(x-4), I did it the other way round. Woops.

What mark do people think is needed for 100UMS?
17. (Original post by tsr1807)
I got the same
18. Dunno if i am the only one but i didnt find it too bad.
In all fairness though, yesterday i did 2012, 2013, 2014, 2015 past papers, And even with harsh marking didnt get less than 59.
The questions on this 2016 paper were exactly the same layout as in the past so it was quite easy to just memorize the method and sub the nembers in for each question. As soon as we were told we could start i looked through the book and was relieved that it was the same layout.

I must admit this year was my retake because last year i did vertually no revision and flopped it horribly.
The only question i stumbled on this year was question 7 as my final answer was 11.5 not 11.25 but otherwise im quite happy with how that went.

Well like at least 72...

Hope it's 73 (or less). Full marks for 100 would be a bummer.
