Last 3 years it has been 55, 59, 55. So i'd say between 55 and 60. :h:

This paper was quite hard compared to other ones so hoping its lower.

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? :frown:

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 :giggle:

) But yes. I do hope they are on the lower end this year. :yep:

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

I found, if anything, it was nicer than I expected :dontknow:

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 :rolleyes:

I didn't find it that nice :lol:

Fingers crossed for nice low grade boundaries :yep:

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

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 :smile:

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 :colondollar:

Looking at the unofficial mark scheme I've only lost 1 mark :biggrin:

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.

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.

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.
