IGCSE EDEXCEL MATHS PAPER 4H Unofficial Mark Scheme

It depends on the examiner, but if you are talking about the probability one, as long as you have shown that you were figuring out the right suff, just used the wrong fractions, you'll likely get the ECF or will only lose 1 mark.

Wasn't Q1 3n+7 because the sequence was 7,10,13,16,19,21 etc?

I think for part b of the Venn diagram question it was 5/9 and not 9/64, as it asked the probability of the students who both owned a desktop and a laptop to also have a tablet.

Did anyone think this was a really nice paper?!

More... I would estimate for that paper:
A*=85

also, can you remember the 2 values stated for m and p?

what do you guys think an A will be? ;((((

Just noticed - 22a is wrong.
It was 2q - 5p
Because it was 1:4 in ratio, where 1 was equal to p, so the entire line was 1+5 = 5p

Nope.Never been above 82,And it was not the ''easiest'' paper ever.

No you are wrong. That doesn't fit in with the last question.

Yes it does - it asked for ON.
OM was stated as being p and OM=1/4NM
Therefore NM = 4p and OM = 1p, therefore, ON = 5p.

And that definitely fits in with the last queation which asked about QR and OM being parallel - 22)a had no effect on any of the other questions.

I'm pretty sure it was 60 degrees
