Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme

Scroll to see replies

For the circle theorem question I assumed the angle given was the alternate angle to the triangle and used that for calculating the other angles and gave correct reasons e.g base angles in isosceles are equal, angles in a triangle, tangents hit radii 90 degrees etc. Can someone please tell me how many marks would I get? Thanks

What would I get these marks for? Can't believe I got this wrong.

Would you say that one of the bad things about the sample is that it is a leading question?
I put it because the word often was in the question and one of the response boxes which may suade people to pick often.

For the crisps question I put "How many crisps do you buy each week"? With the answer boxes would I get full marks?

Has the foundation unofficial markscheme been completed yet??

No, because someone needs to be able to get a copy of the paper like they could for the higher.

the paper was easy

Guys see for question 3c - do you think it is ok to say that he only asked people in that specific age group, so it doesnt give an overall representation of how many crips people buy as a whole?

Think you made a mistake in q2 (b), the rotated shape is one unit too high, the bottom right point should be at (-1, 3).

May have been mentioned before in the 108 pages!

No, you're wrong, although both are divisible by 25, doing so would change the actual value of the end answer. The final answer is 100-25 pi

lol what... you never heard of factorisation?

Does factorising still count as simplest form? I'm always unsure so I never do it and I left my answer as 100-25pi

That is the correct answer bc if you do that on the calculator it equals to 21.... and if you factorise it down to 25(4pi -1) you get like 289.... which is incorrect.

Because it doesn't factorise to that. It factorises to 25(4-pi)

For the reflection and rotation questions, will i get 1 mark each? becuase i reflected on of the shapes correctly but i placed it somewhere else, and i also rotated it correctly but placed somewhere else
