GCSE Maths UNIT 2 AQA + UNOFFICIAL MARK SCHEME 2016

Original post by Bulletzone

There was a number machine question which involved you using Simultaneous equations to solve a and b.

I have the answer but can't remember the question, If anyone can tell me I can add it it.

The question was something along the lines of:
a (x3) (-5) = b
and when the input to the number machine is a+b the output was 64

@Bulletzone there was a question or two on surds; you had to rationalise the denominator for one of them and the other involved expanding the brackets to get an answer in the form a (square root sign) 3.

Yeah I got 28-(10* root 3), which is what everyone else I know got too.

My friend worked out that on average, you needed 83% across all 3 papers to get A* (based on the last 3 years).

My teacher says, as a rule of thumb, that half marks is roughtly the start of a B grade.
So if your confident about ask your answers until the staple, you should be ok for a B atleast.
Don't forget all the marks from all the papers get combined for your overall grade.
The most marks come from unit 3, where you can get upto 80 marks of the overall 200 (across all three exams).
So rather than worrying about what you have already done, focus on doing the best you can in unit 3

Hope this help

Yes it is, but you might have done the linear exams instead of this exam, so you should probably make your way over there.

Looks like the unit 1 and unit 2 papers are already available online, i can't open them so must be for teachers only?

Hi ive been doing past papers, then relearning anything I've struggled on. I get 76/80 one paper then 64/80 the next.
I think i only need about 64/80 to get the Astar Im seeking but don't want to leave anything to chance so im getting my head back into another past paper.

Think I'll do some quick 3D trig today and redo circke theroms with mathswatch.

That and doing a past paper will be my lot for today :smile:

What you doing in prep mate?

Just going over A*/A grade topics like Vectors, Cosine rule etc. I get caught out sometimes on the exams so looking at hard questions (big ones like 5-7 markers). I'm not bothering with 3D trigonometry; do you think it will come up?

Reply 37

Im sure trig will come up, may as well go over 3D trig then im covered for both :smile:

I didnt use to understand vectors until i watched the mathswatch video on Vectors, she explains it in a really clear and easy way. Im now seen as a vectors expert in my class and it's fully thanks to that vide! Id definatly recomend you watch the mathswatch vectors video if you a little unsure. She even explains how to prove 3 points form a straight line.
Vectors are fairly common and are worth quite a few points.

Good luck tomorrow mate, hope to see you here after the exam
