24 hours have passed so here are full solutions to the 13th May IGCSE Maths Paper 42. These are my (IGCSE maths teacher) solutions and not the official solutions from CIE.

I’ll try to answer any questions regarding this paper but...

Since I don’t want to make any predictions that could be wrong, I will not answer any questions like, 'What will I need to get this grade?' or 'How hard/easy was the paper, what will the A boundary be?'.

I’ll only say that I thought it was a very hard paper, one of the hardest in recent years.

Here are the average total grade boundaries over the last 2 years:

A* : 174.7/200
A : 145.6/200
B : 114.8/200
C : 84.4/200

You can see my solutions to Paper 22 here.

i have got about 151 in both is that considered an A, i think A boundary will be lower than 145
do you think Sir ?

Sir i used the correct formula for the radius question but added some something extra for the height so got a wrong answer so how much will i lose
and also for the arc length i calc. the arc length of the minor arc correctly without any mistakes so how much will i lose for these two questions.
