God, you lot are funny.

Stop stressing, it's over. There's nothing you can do about it now. Even if you get the end result to questions wrong, they do give out marks for your method you know. Anyway your final grade will not only depend upon what you get, but how the paper is handled by the rest of the country.

my favourite was what is log to the base 6 of 36. Personally I thought the paper was fair to moderate.
Yeah i liked that log question... I looked at it and didn't twig that 6^2 is 36 so I looked in the formula book for the logs do different bases formula thing and did it that way!

Oh well, still finished the exam with 45 minutes to spare... it was WAY too short...

Oh crap...

5. y = 3^x intersects at 0,1. Area = 1.82... (under curve)

I remember they asked for the coordinates for the y-axis.

I just labelled it on the graph '1' where it crosses the y-axis.
Is that the coordinates? Or do i hv to say its (0,1)??

Hello. Sorry about this.
But can anyone help?

Does anyone remember how much the sequence question on C1 was worth?

technically, just writing '1' isnt a co-ordinate is it? (0,1) however is. I doubt you'll get the mark for just simply writing '1'. However it was only a two mark question, presuming you drew the graph correctly, you'll get 1/2 marks

The last question of C2 was just evil.

I couldn't factorise the differential or whatever it was called, i just couldn't think of the right number and it took me 20 minutes to work it out, then I didn't have any time left to finish it, but I'm not too worried.

I GOT N= 14!!!!!!!!

I love the questions that go "prove your answer equals this" because it does equal that and then you like get marks for assuring yourself you're doing fine lol

If you said "it crosses the x axis at 1", then you should get the mark, well you bloody better, because thats what i wrote :P

nlog.8 is less than log.04

log.8 and log .04 are both negative.

the sign reverses again

its the fact that it was the real AS exam which makes evry1 blank out/ make stupid errors that we'd never make doing practice papers.

for C1 simultaneous equation question worth 7 marks i did it all right, wrote d=2/5 but then subbed it in wrong and got a=2 (when a was actually 5) so im a bit annyoed at how much marks i'll lose, im guessing about 3

Surely it's "it crosses the y axis at 1"?

could someone explain how we were meant to work out the area (the last part of C2 exam)

i found the points of intersection of line AN and the curve and integrated the two equations combined and got the wrong answer (800/81)

cheers

a1 = 3,

an + 1 = 3an – 5,

5
E Ar
r=1


how do you work this out?

is that n/2 (a+l) the right way to do this?

i did

E 3r - E5....

the easiest method is to split it into two shapes. First from A draw a parellel line to the y axis, so you're left with a triangle and the area from O to A. You then integrate from O to A (between the limits of 2 and 0), and then you find the area of the triangle, which you can find the dimensions off, because you know the co-ords of A and B, so you can find the height and width. Then add those 2 areas together.

cheers, it all seems so easyy now..that was the logical thing to do.

instead, i found the area enclosed between points A, B and N, will i get any marks at all out of 5 for that, or is that 0?

Last questionwas easy, but i did integrated the full way at 1st, but corrected it. Which question was teh loga 99 one, forgotten. Cudnt work out that N one, but yer my mates got 15, proper annoying, reckon i cud be 85%+ in that touch wood.

Does ne1 reckon it will get UMS'd?? And go up or down??

Did anyone seem to fly through the paper up to like question 7 in like half an hour, then bout 8 onwards took most of the rest of the time?? Crazy.
