# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme Watch

1. (Original post by MehdiK24)
For the overlapping and time frame part you would get full marks as the answer do nkt need to be in context. For part b they will knock down a mark because you said 6+ which means 7 OR ABOVE. Therefore there is no choice for 6. Part c they should give you the mark.
For thr varnish questiom you need to show how you reached you reached rhe answer of 7.5. marks in rhat question will also be awarded for your ability to find the area of a combined shape. In that you may risk to lose one or two max marks in tot
I have only 3x2.5 which is 7.5 and gave them answer as she doesnt have enough.
Also you know the probablilty, i got 0.05 wrong as i wrote 0.5 will i still get 3 marks or is it possible i get 2 marks right from there.
Also on standard form question i have done right working out. But i wrote the answers as 0.7x10^8 will still get full or it will be awarded as 1 mark.

The probability question part b had an answer of 0.04 so i am now assuming that your 5 was a typo for the sake of this conversation. If you wrote 0.4 you get penalised only by getting one mark off. If you had the correct answer of 0.04 you would be getting full marks. Or on the other hand if you are referring to part a, then writing 0.5 instead of 0.05 would lose you marks in part a too, as well as to part b if you preceded accordingly, and i assume you did 0.8 * 0.5 which gives the wring asnwer still. But you would be getting marks for the rest of the diagram and recognising the 0.8 in your part b calculation, as long as your 0.8 was also written there.

The standard form question you would get penalised by getting one mark off.

For the varnish one you would be getting some marks off because as far as i can tell from what you said is that you have only worked out 7.5l as what she has and compared it with 10l needed. The examiner would not know where you got the 10 from as that answer had a few marks behind that would have been obtained by the working out.
3. If i wrote 3b-a for question 23 wud i still get the mark?
4. guys its done, go n revise for paper 2, wait until 24th august for the grade boundaries and til next year for the official mark scheme ffs

For part b then absolutely yes. It does nkt make a differnece abt the order at which your vectors are written

What do you think how many marks do we need total to get C, i think last year was 65 this year it will 70 marks for C
7. I think a C will be 62 marks.

No they just asked for the answer in terms of pi
Phew! Thought I lost a mark there!

idk maybe around 85-90

My teacher gave us a potential list:
simultaneous equations - linear and quadratic
trial and improvement
stem and leaf
solving equations
trigonometry
sine + cosine rules
scatter graphs
factors, multiples, primes
length, area and volume formulas
number sequences
frequency polygons
histograms
area + circumference of circles, sectors
volume, surface area of 3D shapes
box plots
bearings
upper and lower bounds
angles - parallel lines, polygons
stratified samples
percentage increase, decrease or % backwards
HCF and LCM
mean from a frequency table
ratio
recurring decimals to fractions
compound interest
rearranging formula
pie charts
pythag theorem
moving averages
cumulative frequency
sine and cosine graphs
algebraic fractions
x^2 + y^2= 25 circle equation
completing the square
number proof
transformation of curves

i thought they dont do moving averages anymore

IIRC AQA and OCR still have it, but Edexcel doesn't.
13. What do u think the grade coundries to get a C would be
14. (Original post by PCB)
I think a C will be 62 marks.

I believe it will be more because last year was 65

25th is results day, 24th grade boundary release hny
16. I got 47 marks on this paper how much will i need to get A overall on the next paper?

An 'A' is predicted to be around 135 marks ish (predicted by my mum whom is a head of maths at Manchester grammar) so 88ish marks but to be sure aim higher.
18. Couple of questions, if someone can help:-

1. For the square inside the circle, I thought they were asking for the area of one shaded bit, rather than 4.

I wrote 100 - 25pi, then in the next line, (100-25pi)/4 What do I score for this?

2. For the construction questions, I only put in my construction lines for the intersection, not the preliminary ones. Do I score any marks at all?

3. For the mid-point question, I misread the question as trying to find the mid=point of the two co-ordinates given, instead of reading it as the mid point. I calculate correctly to find the mid=point though. I assume I score 0/2?

Many thanks
19. For Q10 (mid-point), I found the mid-point by using the same method when finding the median in a small set of numerical data... I didn't know how to calculate it using algebra but check the attachment for an example of how I found one of the variables.

Would I get full marks (2/2) for this? My answer was (-3, -2).

Or you could just solve it like an equation...
