# UNOFFICIAL MARKSCHEME Edexcel Maths Calculator paper 09/06/2016 Watch

1. (Original post by Aol1)
Anyone know how many marks I will get for putting 9/20 for the 2nd question instead of 0.45?
You will get full marks on that question cause the mark scheme will say 0.45 or the equivalent
2. I love how I got the simplest Histogram wrong xD how much do you think it would be for an A?

I would think you would lose 1 mark. It's a just stupid mistake like me who forgot to put a god damn ass key in the first question! The amount of past papers I've done and I forgot to put a key!
In the exact same boat as you. Never forgotten before and I have a feeling this might have just dropped me an A* overall :/

do you think i would get the mark for 1/(-3x-4) instead of -1/(3x+4)??
I hope so, as this is what I got. I don't see why not, they're both as simple as each other!
8. Did anybody else get an N shape for the graph question? That worried me because I swear my table was right
9. It doesn't seem to open???
10. So now we've done the papers, what do you think the grade boundaries will be? I think I got around 173-180 lol

Yeah but it should be drawn as a smooth curve because it's a cubic graph

Anyone have predicted grade boundaries for this paper??
probably 67 for an A, maybe 83 for an A*

Yes. In further maths, you learn that quadratics have two solutions which causes the arc shape and cubics (anything with a power of three) has three solutions and so turns twice rather than once.

Yes they are the same thing just multiplied by -1/-1
17. what you just did was stating that the area had equalled 45, when in fact it said the perimeter equalled 45
