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.

Do you have paper 41

Thank you sir for your efforts.
I had a question in regards with the significant figure
How many marks are going to be deducted incase i did not give my answer to the 3 significant figure mentioned at the instructions?

That depends on the question and what you actually wrote.

In the question asking for proof about the triangles being congruent I mentioned two points but left out the one about the tangents in panic over the difficulty of the rest of the paper. I wrote instead that if two sides are equal the third one is bound to be equal too. Will that be accepted, Sir?

you might lose a mark there

i didnt understand the last question on probability i thought it said the chance he wears not all three at same time so i multiplied the chances of wearing hat with scarf and with no gloves.. so i'll get 0/3?
