IGCSE EDEXCEL MATHS PAPER 4H Unofficial Mark Scheme

Thanks man! Yea I'm definitely aiming for the A*, that test was actually really easy. Got majority correct apart from that and the hcf and lcm question, let's just wait and see now! 😂

Does anyone remember what question 4 Was?

It was the parallel lines with the angles being 53 and 60, and then the hexagon where you had to find the value of x.

Thank you! I thoughy it went better than the 3h but for some reason the venn diagram stumped me so I didnt get any marks for that. :-(

Oh well, it was only 4 marks, yeah I found it great, I only fell down on the HCF and LCM question for some reason haha.

Which number was the hcf? First ever vector q right!

I think it was 10 :-(. Ah well, lets just forget about it till results day.

Good idea. :-) only 1 more exam to gi!

HCF was 20 and LCM was 420
And how on earth do you only have 1 more exam?! xD Bruh I still have 7 exams left

They are parallel because vectors are quantities which represent magnitude and directions, hence multiples of the same vector are parallel.

I think I might have got LCM 420! Only History paper 2 ocr on Monday. I've done 23.

Do you do geography then?

HCF was 60.
