and why wouldnt 1.7 be accepted, just looked at a past paper, and the range was a deviation of 1 from the correct answer so if it was 1.65 the raneg should be 1.6-1.7

You'll lose 1 mark for 19 and I'd need to see all your working to know how many you would get for the percentage question.

ok i dont remember how but i just didnt get 184 i got i think 22.4 if my gesture is precise

 

[Ijlal Amir]

I got 177/200 Hopefully I'll get an A*

ALRIGHT THANKS. BUT SINCE THIS YEARS PAPER(MATH 42) WAS HARD COMPARED TO THE OTHER YEAR WILL THE GT BE LESS

Read my first post. And even if you write in capitals, I'm still not going to discuss it

 

[notnek01]

about finding the profit, Sir i did all the working correct showing the correct answer in the working but i wrote 84 instead of 184 in final answer line but i have done all the working as done in the paper 4 post by you.

You'll lose 1 mark.

You said 2.7.

But even 1.7 may be outside the range.

4/9 may be in the range, I'm not sure.

4 mark questions often require you to round correctly so you may lose a mark for 1743.85.

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.

Thanks for this and the paper 2 pal! It actually made my day because I did better than I thought I did
I wish everyone good luck
