I took higher and it was easy!! Really annoyed vectors wernt on it cause i revised that the most. But anyway much easier than Non-calculator ;D
There was a question on higher on vectors, im sure there was. towards the end
4. Re: AQA GCSE Maths - 13th June 2012
does anyone know the answer to the question where you had to find the mean number of minutes taken to get to work? it was in the middle of the paper

There was trig..The trapezium question!

Yep, you plot the mid-points.
The trapezium didn't require trig, people over complicated it. It was simple proportion.

No there wasn't.
7. Re: AQA GCSE Maths - 13th June 2012
was the answer to the last question 8/33
and i swear the second to last question was wrong as it said prove it was 2-8n over n(n-2) but i got 2-6n over n(n-2)
8. Re: AQA GCSE Maths - 13th June 2012
Did anyone actually take foundation :/

if so what did you get for finding the height of the 3 blocks? The question went something like you need to estimate the heigh of the blocks if there were 27 of them. I'm not sure if this is correct but I did

Length x width x 27 (as a height)

Wow, really?

What did you get as the answer?

It's 8/11.
1/11*3=3/11
1-3/11=8/11

You do -n * 2 which is -2n which actually gives -8n.
Instead of n*2 =2n.

It was a matter of negatives (: I got confused too at first

yeah there was! It was the last question!

The last question was a probability question. I think you sat a different exam to me. AQA, linear, paper 2 (calc) higher?

Wow, really?

What did you get as the answer?
Yup, I think I got 55cm^2?

Basically you did 12/8 (two sides you knew from either triangle) to find the scale factor, which is 1.5, and then used that to figure out the other side by doing 11 * 1.5. Now you have all the lengths needed to calculate the area of each triangle and subtract them from each other.

I did foundation and I do not remember this question : ( I have screwed this exam up completely.

Gosh, I did some long winded method -.- And yeah, my friends said today they used similar triangles. At least I got the same answer! (:

Ah, apparently you could use similar triangles to work it out though.

So no trig involved (:
19. Re: AQA GCSE Maths - 13th June 2012
Oh ok cheers- tried to do similar triangles but failed- hopefully get a few ,marks for working out!

I think everyone else here did linear. Did you do modular? The one where the last question was vectors on a trapezium and there was a freaking huge 7 mark trig question? :P
