# How hard did you find the Edexcel GCSE maths paper today? 2011

How hard did you find the Edexcel GCSE maths paper today?  I messed up on the triangles I'm sure the answer was aas, because we had two 90 degrees and a shared side!  Also the ratios for the vectors was tricky and I'm sure I messed up with constructoing a line!  I realised I could have done it the minute I left the exam hall!

I deducted all the marks from the four I know I got wrong and got about 81 %  (basicly minus 19 from 100 as its out of 100).  I am an A* student.  How any A* students found it hard/tricky?   Hoping you all agree then hopefully the boundary will be lowered to 70%  !   Wishful thinking!

My dad was saying there was something on the news about the maths test. Apparently Edexcel messed up some A level paper with impossible results and were accused of making the maths paper too hard. I guess that's why I found this one so hard :S

How did you do on the others?  I think this one was harder! I hope they put the A* mark at 70!

This was first paper, and calculator one on friday, if its has hard as today's I've failed!

Answered Mon 6th June, 2011 @ 17:02 by JNicole

don't say you've failed, cause you won't have done :) the grade boundaries better get lowered for everyone to achieve a good mark :) i got 5.40 for that one about the money sharing :) x

Answered Mon 6th June, 2011 @ 17:05 by Kelly:)

Yes thats it I also got £5.40.  How was that vector proportion and proving it was linear for you?

I also figured the two triangles were congruent because they had two angles and a side in common therefore making the angles the same

Answered Mon 6th June, 2011 @ 17:08 by mbismbis

i guess it was ok, but those four weird questions, i'm pretty sure we hadn't learnt them...:S esp the surface area Q - i think they shouldve put the slant height :(

I got told by my maths teacher that if I didn't get an A*, I'd be buying my own body bag. I'm in a minor state of depression at the moment so I'm now looking up body bags instead of doing science revision. I just have to ace the calculator because I found it difficult to restrain myself from crying in the exam hall. Fun fun fun.

Answered Mon 6th June, 2011 @ 18:43 by Jess

hopefully this years grade boundary will be lower as my whole year group came out that hall complaining that it was hard which it really was >.< im glad im not alone! the amount of hours i spent revising and it was still so hard, gosh! now we have calc =/

Answered Mon 6th June, 2011 @ 18:52 by nat

It wasnt too bad, just harder than all the past papers. They just used difficult questions which you should be able to do and then added another little twist. E.g. the cone and hemisphere one, you should have been able to find the Length, l, as 2x. Then its a right angled triangle with the hypotenuse as L (2x) and the base as x, and you need to find the perpendicular height, h. (2x)^2 = x^2 + h^2 using pythagoras, and then 4x^2 = x^2 + h^2. So h^2 = 3x^2 and h = root3 x.
a couple more required thinking quite a bit, like the vectors which should have come to 6/5(a + b) and so it is a multiple of a + b and so is parallel. And the surd one needed a strong understanding of surds. i think the answer was -3 + 4 root 2 so a was -3 and b was 4.
overall, yes the paper was difficult and i think the grade boundaries will be lowered, and fridays should be easier. Good luck everyone hope you get what you want :)

Answered Mon 6th June, 2011 @ 17:03 by shafiqur rahman

cant remember exactly, i worked it out as an equation and got x=£5.40

along the lines of £30 something?

Answered Mon 6th June, 2011 @ 17:06 by JNicole

I got the 3 boys one.  You had to work it backward.  x being the first proportion.  I ended up with something like this:

x is ben

2x  Is the person who got twice

therefore 3(2x) is the person who got double the last guy:  Therefore:

x+2x+3(2x)= 57   (i think the total was)

therefore 9x = 57 eg.

Then work out the proportion for the ben or whatever his name was

Then solve it as

Answered Mon 6th June, 2011 @ 17:13 by Natasha Naeem

That triangle one for construction:

-First make a mark exactly the same distance as the length of the base, forming an isocoles triangle.

-Next bisect the angle P, by making two marks on the lines that make it and finding where they touch.

- Draw a line through and you have your angle!

Only figured it when I left!

It was so difficult! I was right at the back of the room and I could see people convulsing with sobs! Incl. all the A* students! Fingers crossed they lower the grade boundaries!!!!

Found it extremely difficult, and I've been A* for a year solid now :/

The question on vectors and the surface area one were the worst, but they have to lower the boundaries because most of it was far too complicated for GCSE, in my opinion anyway, lets hope they see it that way :L Thought some were ok though, although the whole paper seemed a bit data heavy to me.

Have to admit I had a little cry, hope thats not my grade down the drain, we shall see what Friday's calc brings

It was very difficult i thought... but as everyone else is saying, I am very certain that the grade boundaries will be lowered down... BTW what did everyone get for the last question on higher tier?? I did not understand that or the vectors question!

Hoping the calc paper will be easier.

I did the exam, the hardest question was the part b on the vector question but i think i somehow got away with it. i found the cone and hemisphere one extremely difficult, i worked out wrong and so i had to ask for additional paper. in the end, thankfully, i got H=2x. What  did people get for the percentage question, i done (1500-250)/250 and then times by 100. this gave me 500%. Percentage change is the increase divided by the original amount, multiplied by 100. lots of people got 600%.

Answered Mon 6th June, 2011 @ 20:03 by dfdfd

all of the algebra was very easy, i think i got K=-2t/t-1, i loved the simultaneous equation question. for the coordinate question i got 5 as the length of the line. what did you get?

Answered Mon 6th June, 2011 @ 20:08 by dfdfd

Sarah, yes I agree, there usually are a lot less thought devouring questions!  Judging by everyone's comment the boudries will be lowered.  Just spoke to my class, everyone said it was hard.  Hopefully the whole country found it so!

Luis, that vector question should have resolved to something like  1/5(a+b) therefore proving that it is parallel if it does not share the same point.

sana haq, I agree totally! I say we all start a union or movement or something, lets all march down to Edexcel and demand they lower the boundry!

Viva La Revolution!   :-D

Answered Mon 6th June, 2011 @ 21:05 by A100

@ Adam, you don't necessarily need to have an an A* in both, but you certainly need at least a high/ good A* in one, and at least a very high A in another, I think. If anyone knows more about this, please say!

I thought it was OK, but I did notice that I had to work a lot harder than normal.

Everyone else came out saying they failed, even the people in top set, and I go to a grammar school.

They will lower the grade boundaries, they can't put the A* mark at 80 if nobody got it.

Hopefully the calculator paper will be easier.

P.S. I noticed that they put at least three questions in it that involved a lot of thought when usually it is none or one!

no one knows the grade boundaries yet! it totally depends on how the rest of the country found it and it's moderated on that. Did you mean the UMS was out of 100? and the actual marks were out of 60? cos that's what it said on my exam paper.

Exactly for me ! its so devastating to see an A* student , who has been like me for the whole two years , walk into the exam having done LOADS and then find the paper hard. Usually a past paper would take me 50 mins and this time i didn't even have time to check my answers! Like you i'm hoping for Friday - but we're all in the same boat. My twin brother is a maths genius and even he found some of it hard- my teacher said it was hard and all of you.
