New Maths GCSE is properly hard isn't it?

[Somerville]

I've seen this discussed, but I only just clicked how much harder it is. DD is revising, and has been given a maths past paper to do, but no answer booklet. So she asked me to mark it.

I have maths A level, but struggled a bit

Differentiation, 3-d trig, factorising quadratic equations??! I'm sure I didn't do any of that at GCSE (in mid 90's). Is A level harder too?

Does anyone know what percentage of questions they need to get right to get an 8 or a 9?

For a nine we have been told you need to get all the questions right, allowing for dropping a few marks for carelessness here and there. Sounds about right.

So does it go
90 per cent for a 9
80 for 8
70 for 7
60 for 6
50 for 5
40 for 4?

No it doesn't. Cant give a better answer as not an expert but it isn't that simple.

Fair enough.. Thanks anyway

Last year for Edexcel's Higher paper you need the following %:

4 17%
5 28%
6 40%
7 52%
8 65%
9 79%

Thank you, this is really useful
