Edexcel A2 C4 Mathematics June 2016 - Official Thread

For an a* what do I need to get average in all my other modules roughly? Do they all have to be over 90ums? Or can I have dropped marks and they look more at c3&4 grades?

To get A* you need an average of 90 UMS over C3 and C4, e.g. 100 in C3 and 80 in C4, as well as an A overall, which is 480 UMS out of the total 600 UMS.

So you could get 100, 100, 80 at AS level, 100 in C3, 100 in C4, and zero marks in your last unit, and get A*.

If I get 60 in c3 and 65 in c4, I've lost the A* havn't I?

I'm sorry mate, 60 in C3 is barely an A. And 65 = around 85 UMS. But hey, still an A

well 16 is incorrect, you must've made a mistake somewhere

I know what I have done now I didn't realise the 4 cancelled and took it out as a 2 oh well bit silly

Hi everyone, just wanted to ask if i can have this split

C1234 D1 S2

FP12 S3 S1 M1 M2

From what I know, you are not allowed to use any lesser modules for further than single, so u would have to swap S2 with either S1 or M1. Not certain but from what my teacher told me this is the case

Do you think that 60-65 in c4 and 70ish in c3 could get me an A* ?

How many marks would I lose on question 3 if I did not put dy/dx after I differentiated the cos pi? I differentiated all the rest correctly, but this meant I also would have got part b wrong as well :frown:

If we assume that you'e satisfied the C3/C4 condition for A* in the worst case scenario (i.e 180/200) then you just need 480 - 180 = 300 UMS from the other 4 modules, which is an average of 75 across 4. So you can afford to make mistakes. And the more you get in C3/C4, the lower this average is (if you get 200/200 then it's an average of 70 across 4, for example).

Hi, for question 6 ii and iii I worked out the value of Lambda to be 16, I forgot to divide by 2 :frown:

so i carried on to working the next question out with the value of lambda of 16. (the actual answer is 8)

However my working throughout is perfect, i just forgot to divide lambda by 2. Will I lose just two marks for accuracy?

I haven't looked at the mark scheme or the questions, so I would just be guessing. I know exams are stressful and people are trying to count their marks / predict their grades etc but personally I wouldn't bother. Just enjoy your holiday if you can.

Its similar to question 6 here, expect my value of K was wrong, and I used the wrong value of K to carry on the question.

For 6A it was 6 marks to find lamba

6b, 4 marks to work it out

I apologise - I know that this is important to you but I can't help. I would, however, say you'd probably able to make a fairly good/accurate judgement based on the mark scheme of that question. Good luck though :h:

(it is always worth asking someone else who knows more about these things).

Any well thought out grade boundaries?

guys question 5a was it t=pi/3 or something and you plug it in to dy/dx to find the gradient? and does anybody remember exactly what question 5 said? and the x and y equations?

yes a)dy/dx at P(4root3,15/2)
b)point where dy/dx=0

x=4tant
y=5root3 sin 2t

i remember bc i spent ages in that question.. i got t=pi/3 when i sub x value and t=pi/6 when i sub y value .... so i did both.. i hope i didn't get zero

Not necessary - it felt neater to me, so I wrote it, but leaving it as two logarithms +c is fine. Even writing it correctly as two logarithms and then combining it incorrectly would still get you full marks.
