8th May Maths Paper 2 full solutions

[himanshu dave]

I have a question in the paper the question was gg(3) and we had to simplify it I was right till the step where it comes 1 upon 2(1 upon 2x) it was for 2 marks will I get one mark????

 

[himanshu dave]

excuse me....I think ur line of best fit is wrong...there aren't equal number of points on either side!

Hi,

24 hours have passed so I can upload my solutions to Paper 2.

If you have any questions, I'll be happy to answer them.

- I will not answer any questions like, 'What will I need to get this grade' or 'How hard/easy was the paper, what will the A boundary be'.

(This is Paper 2 version 2. If anyone knows how to add this to the thread title, please tell me).

It changes every year and I haven't seen Paper 4 yet so it's impossible for me to know.

would 170/200 be a A* plzz reply fast im desperate to know so tht I can aim a target for my paper 4

can anyone provide me with pure mathematics mark scheme held on 7th may (paper 12)

You don't need an exactly equal number of points on either side. I decided not to intersect one of the points above the line because that would've moved the line a bit too far away from the points below it.

Of course, there are many ways to draw the line to get the marks but I think mine is very well drawn, in my humble opinion

I think you will get 1 mark but I'd need to see all your working to be sure.

Does your teacher not explain to you that the grade boundaries change every year?

It is impossible for you, I or anyone else here to tell you what you will need for an A*.

 

[notnek01]

but i
people dont understand that the grade boudries depends on their marks! the threshold is calculated dependent on how good the students have performed..... how many of ur students achieved a full score?

This is irrelevant since no one has taken Paper 4 yet.

Even after Paper 4, it's very hard for anyone to judge what the grade boundaries will be, which is why I'm not going to try.

 

[notnek01]

i meant like in this paper! and where are u from?

Grade boundaries for individual papers don't really mean anything. It's the total out of 200 that gives you your grade.

I'm from the UK but I teach in Asia.

Ill prolly lose a single mark I wrote for the simplification part
(1/1/2x)^-1 its right basically but it depends on the examiner !! Insha Allah , He'll give me full

The question asks for the answer in its 'simplest form' so you will lose a mark if you didn't write x.

 

[himanshu dave]

this is my working

1 upon 2x
= 1 upon 2(1 upon 2x)
= 1 upon 2 upon 4x (took the 4x on top)
=4x upon 2

I by mistake mulpiplied the 2 to the denominator also......

I think you will get 1 mark but I'd need to see all your working to be sure.

I know but unlike everyone else i inserted this ()^-1 !!

I think your working is incorrect. Where does this come from: 1/2 (1/2x) ?

It's still not in it's simplest form, sorry

I know but Alhamdulilah thats the only Question i got wrong !! xD

Sir, for the loci question for the perpendicular bisectors if I drew the arcs correctly but didn't extend the line to touch the arcs will they cut marks?

You will lose 1 mark.

because it was gg(x) and g(x)=1/2x then it will be 1/2(1/2x) cause like the question is gg(x) so then g(x)= 1/2x then g(g(x))= 1/2(1/2x)
srry bout' the wrong information really srry...
