Hi this is my first thread (FYI). I was just wondering if any one else did the new spec aqa maths exam today. It was the linear one which lasted 1h 30m and it was out of 70 (non calculator). How did anyone do? Which questions puzzled you? what do you think the grade boundaries will be? Etc. I would also appreciate it if some one could compose an unofficial mark scheme.
Regards

Yup I did it. Did it start at 1ish? I did that one. I think it was the same one you did. I know it was linear and non calculator? 27 questions? :P

Yeah I did, found it alright!
For the square formed by the crosses did you get 2cm²?
And for the one where you had a to write a formula for C in terms of n, did anyone else get:

C = n/20 + 10 ?

[jones2596]

And i think grade boundaries will be around:

58 - a*
46 - a
38 - b
31 - c

these are just guesses though and could be completely different

[RobbieHazz310]

i messed up on the C and N question :/ but for the crosses i got 4cm2 as each leg was 1cm2 due to pythagorus' theorem and the height and width of the square was 2 legs so it was the height (2) x width (2) which is 4. I might be wrong though :P

Just gonna go cry in a corner know that I did foundation on it...

Hey I got 2cm² for the cross one aswell and got C=0.05n+10 but thats the same I need someone to put up a markscheme of what they thought :P

[RobbieHazz310]

i think i got around 58/59 which is either a high A or a low A* so i hope i will get A* overall is i tend to better on calc (YN) good luck everyone

Anyone got the unofficial mark scheme?!

For one of the questions i got angle x = 56

The Square question one is infact 4CM2 (4cm squared) as if you read robbiehazz's post infact you do need to ues pytharagoses theorem (which i did)

The hypotenuse was 1cm so i use a2+b2=c2 and c2=1
so everything else must be 1
as there where 2 lines of each side and each side was 1cm
so 1+1 = 2 = 1 side

and then 2x2 = 4 = to get the area.

------------------------------
And for the C and N question that is correct. (C = n/20 + 10 )

I left that question because i was sorta confused and in the final 5-10minutes i actually managed to figure it out rofl. quite easy than i thought.


and @reubs yes if i can remember the angle was 56.

I'll be lucky to have got 25 marks in the paper in all honesty. I totally blanked as soon as I got in.

Does anyone want to hesitate a guess as to how many marks I'd need to get tomorrow to come out with a b if I didget around 25?

But (using pythagoras) 1 squared + 1 squared is just 1+1, which is two, so the hypoteneuse would be root 2. So everything else wasn't one. :/

For the very last question on the higher paper - the histogram question - did anyone get the gaps in the table as:

80 workers = the first gap
290 workers = the second gap

therefore, the frequency density/height of the missing bar was 1.45: 290 workers/200 (class width)

[Danny786]

It was 80 first gap
180 second gap as it added to 800...

[x-Sophie-x]

For the cross question, I got 1.5 cm^2.
I got C=0.05n+10
And the angle was 56.

[jones2596]

I thought the second histogram one was 280 if i remember right...

Yeah thats what i thought! Spoke to my maths teachers and they are sure that the final answer you should get is 2!

uh boo yah ;P

I only need a B but I'm sure I did well on this exam.
A few questions stumped me, possibly the A/A* ones.

The main one I got stuck on was the quadratic equation where you had to use the formula for it, I was stuck trying to figure it out for ages. 5 minutes before the exam ended I realised that the value of (b) was 1, as I forgot you don't write 1x, just x.

I didn't manage to redo it all in time, wrote down the correct formula with the values then time ran out. Should get one mark for that though. xD
(Note to self: Revise the use of the formula for quadratic equations)

I also couldn't do the questions with surds, just can't get my head around them.

Currently taking a break from revising for tomorrow's exam, the calculator paper is my favorite! :P I just love trigonometry with sin/cos/tan, I find it fun :P.

As paper 1 didn't have vectors, I bet tomorrow's one will - I hate them, just can't figure them out. Guess I'll revise them next.
