# AQA Maths Calculator Paper watch

1. For the histogram I guessed and put 105. I found the frequencies of all the bars ad it came to 315..so i guessed <70 must have been 5. but anyway i found 105 in the end, wrong i guess.

For the interquartile of the histogram, what did you all do? I just did 3/4 of 150 minus 1/4 of 150. Is that wrong too lol?

Last question, I drew y=1 and y=x+1 i think. Or was it x-1. cant remember.

Aliens, completey messed up.

Moving averages, thought it wouldnt come up. Grrr. Put 100 for first part.

The algebra near the end of the paper, I thought oo yay I can do them so in the end i used to quadratic formula, maybe I shouldnt. Did anyone else end up with 30x² - 5x -15 or something like that? And then i did 5 ± √ 265/60. Anyone else? I got some weird answers anyway, dunno if that was right.

Overall, it was wayyyyyyy better than Paper 1, i made far too many mistakes on that.

OH MY GOOOOD THE QUADRATIC FORMULA I TOTALLY FORGOT ABT THAT AND I SPENT ABT 30 MINS AT END TRYIN 2 FACTORISEE OH WELL THATS TWO MARKS LOST

lol that always happens with me. but i kept forgettin how to use the quadratic formula. do you divide the numbers first and then square root or square root it all together
4. Yeh that algebraic fraction question I got it down to a "normal" quadratic but couldnt factorise it. I knew it needed quadratic formulae thing but I don't like using that so I just left it And plus I was on an additional sheet and didn't have room, I didn't wanna ask for ANOTHER additional sheet.

That last question, did you have to put the values. If you did then that is some EASY marks losts, seen as I had drawn the graphs correct.

i didnt use additional sheets lol, i just sort of..made a mess.

Yeh you do, you had to find the solutions of x.

I saw the Histogram thread last night, didn't pay much attention to it HOPEFULLY I got it right. I think my method was a bit "obscure" though.

I knew that would come up!
7. Yea, that last question. WHat did yous get for it and how did u's do it. I never learned it but i think i got it right.
8. That exam was so easy, I finished with 45 minutes to spare

Bit mean with the paperclip - you think "oh that's 2cm" when its actually 1.9.

with regards to the paperclip can u remember what answer u got??

Hey Olican, do you know the grade boundaries for the other AQA Mathematics B (Modular). I think these grades are for the non-modulars. Thankx loads and good luk for your other exams,

Rudy!
Yeah, here they are, from 2004...

A*

Mod 1= 31/40
Mod 2= 20/24 (for both options)
Mod 3= 45/64
Mod 4= 23/24 (for both options)
Mod 5 P1= 47/70
Mod 5 P2= 41/70

A

Mod 1= 23/40
Mod 2= 17/24 (for both options)
Mod 3= 33/64
Mod 4= 20/24 (for both options)
Mod 5 P1= 35/70
Mod 5 P2= 31/70

B

Mod 1= 15/40
Mod 2= 14/24 (for both options)
Mod 3= 23/64
Mod 4= 17/24 (for both options)
Mod 5 P1= 23/70
Mod 5 P2= 21/70
11. Bit of a random question...The coursework is worth 10% of the final mark, is it not? So if one got A*/A* on their coursework, could this possibly be a difference between one grade and another? Say, for example, if one got an overall C in the exams, could the coursework grades bring it up to an overall B grade in maths?
12. Its 20% or 10% per piece.
But yes, that is how the coursework works, but of course if you didn't do particularly well on your coursework, then you can't always rely on it to bump you up a grade. Also, if you got something like 70% on the coursework, and around the same on your exams combined, then there won't be much difference, although you may increase by a few %.
13. Yeah, it was much easier than Paper 1 - I could at leat attempt every question on it! I'm now confident about my A, but I'm sure my other paper was a B. The one today might even have been A*!!
14. I do believe that it was easier than Paper One, however this could be because I was able to use a real calculator opposed to my own brain! lol

I can't believe that much of the "more complex" stuff such as the Cosine and Sine rules were not on the exam, but in a way its better as hopefully my grades will be better than expected!

Stef

P.S Are the grade bounderies the same for Paper One and Paper Two? Or do they both have their own seperate grade bounderies?

Did anyone else end up with 30x² - 5x -15 or something like that?
WOOO! I definitely had 30x², don't know about the rest of it, though.

Yeh LOL. I had 30x²+bx and thats it. Cant remember what the b was though.
17. Problem is, whenever I use the quadratic formula, the answers I get never work out when I put them back in.

OMG I got the same median .

No that for the moving average though - £99.5 I think but I had to guess. You're probably right.
didn't you just ahve to but what group the median score was in. i put 90-110
19. Argh, did nobody here study moving averages? They're very simple...

I think that the following is correct:

You could estimate it as it was something like the median was 3/5 along the box which came to 102. I may be wrong as I dont understand histograms (we never did histogram medians did we???) so I tried to be logical.
