# AQA maths core 1, 13th May 2015 watch

1. What did people get for Q 7?
2. (Original post by 8472)
Last 3 years it has been 55, 59, 55. So i'd say between 55 and 60.
This paper was quite hard compared to other ones so hoping its lower.
3. (Original post by starfish5577)
I think I got 9 and -2
How did everyone get whole number co-ords for the simultaneous?

The equation was 5x-3y=-1
The given was 2x-3y+=30 (I think)

Minus them both to cancel out ys and then 3x=-31 so x=-31/3. Riiiiight?
4. I ended up with root 49 so my answer was 7?? This right???

Well I originally sat it last year so it was a resit for me. Generally it was on trend with papers of present in my opinion. Wasn't harder but wasn't easier. I found it easier than last but that was only because since i've had another year or teaching with Core 3 and 4 + more practice on the papers. (AKA ignore my silly opinion ) But yes. I do hope they are on the lower end this year.

I got 55/56 any chance if a B?

I'm pretty sure you got one of the equations wrong.

I found, if anything, it was nicer than I expected
Most of the people at my college (who are all geniuses) were complaining that it wasn't challenging enough and that it was too easy I didn't find it that nice

Fingers crossed for nice low grade boundaries

This isn't correct.
The area under the curve was 108/5
but there was a trapezium
which has 54
so shaded region = 54 - 108/5 = 162/5.
no silly b = 7 was the answer to the circles question when it said work out the shortest distance and it is right
10. I think it was quite a good paper tbh. It was just the cylinder question that threw me off a bit and I miss read parts of it twice. Got there in the end though after 3 attempts I'm resitting the year and I thought it was easier than last year's but that might just be because I turned up to school more this year
Looking at the unofficial mark scheme I've only lost 1 mark

5x-3y=-1 was the equation of the line you found. The gradient was perpendicular to AB but I don't think it passed through A. It gave you the point it passes through to find the line equation.

You needed to simultaneously solve 2x-3y=30 and the line AB given in the first sentence.

Thanks. I'm an idiot.

Yep. Just realised that I used the wrong one.....
14. has anyone posted a unofficial mark scheme?
15. (Original post by Rk2k14)
You too.
Dreading C2 though. Hate it.
I'm hoping core 2 isn't that hard but we don't always get it out way.
How have you revised and what other exams have you got in the near future.

How about clicking on the first page?????

Edit: looks like they merged them, will post my copy below

There was a thread earlier but it got deleted for some reason.
If you look through this thread's earlier pages, I remember seeing a post with all of the answers (and I'm pretty sure they were right since I got more or less the same and it seems unlikely for two people to make exactly the same mistakes). I'm not sure if it's still there though.

This is all that I can see remaining. Seems correct for the most part.

Other one was merged into something or removed.

Looks like one of the most accurate mark schemes so far (couple of errors in it).
