grade boundary predictions
100ums-75
90 ums-68
80 ums-63

Harder than last years? Or easier? Your opinion?

easiest exam so far

For question 7b how many marks will I loose if i did not use n=3 in my inductive step. I just did n=1

I used n=2 too**

For question 9 (c)
I got the y coordinate 6/p +6/q that's the same as (6/p+q) right? I only used 6/p + 6/q because the question said SINGLE fractions...

And I used xy=9 --> x=9/y [y] is that alright?

did you have the label the new vertices of the triangle? ie did you have to say a' is... b' is.... or could you just write down the new vertices?

I think having just the coordinates is fine..

Much easeir no thinking at all required,,however iam speaking for myself,there was this other candidate who had four questions wrong,so he wud considerably bring grafe boundareies low :wink:

Trust me I know how you feel, today I finished early and decided to check my answer to 4 (e) and I had it right the first time but when I was checking it I did spot a mistake although it didn't affect my answer... but then when changing my working for the area of T I did (1*3)/2= 2 so I thought 1*3= 4

Now that's appalling! :mad:

maximum 1 mark,u might not even loose it

Why would you ever need to test n=3 in a recurrence relation like that?
In the textbook unless its a Un+2 recurrence style question they only ever test to n=2 and in every previous mark scheme they only ever test to n=1 no matter what. I highly doubt you would lose any marks here.

probably,its the book which requires you to show the step

Model solutions attached.

Fairly standard paper, perhaps marginally more difficult than standard.

Just come in pist. This cheered me up, hopefully I've done enough to get a 90+ ums in this exam. I think to get the area of t'' I did Qr * coordinate matrice of T and then did 0.5(2*6) or something, would that still get the marks?

Also thanks again for the upload, I've checked your mark schemes for C3, C4, D1, and FP1 now.
