what abt the arc? i calculated minor correctly,how much will i loose?
An 80 in p4 and a 60 in p2 can I get an overall A
are yo24 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 think they r fr previous years!!!are yo
Are you sure about these, total grade boundaries? Won't the threshold go more low, any chances? :S
Yuss, they're!i think they r fr previous years!!!
You'll get at least 1 and maybe 2 depending on your working.Hello sir
I hope you are fine
For the question to find the area of the prism
I found the area of 4 rectangles correctly but I got the final ans 316
How many marks I will get
How do you know BT bisects ATC? This was not a theorem in your syllabus that you can quote without proof.sir ive written angle ATC is bisected by line BT....therefore angle ATB=angle CTB and also explained why others 2 adjacent sides are equal
will i get full marks for this
I don't know which radius question you are talking about.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.
You'll lose 1 mark.in p42 i wrote 19 as the value of n how many marks do i miss?
You'll probably lose 2 marks.what abt the arc? i calculated minor correctly,how much will i loose?
You probably won't get any marks for the reflection.I did reflection on X=-1 instead of Y=-1 , i will lose all marks for that question ?
and in q9 part b, i calculate the speed of water same but with different working , still i can get full mark ?
i wrote some answers to 4 s.f for Example: 1743.8 not 1740, is it still right ?
3.13 will be fine and 2.75 may be fine, I'm not sure.Is there a range of values for the graph question .... i got point P (2.75,3.13) and m as 0.4
If your answer is correct, you'll get all the marks.sir .. i calculated the speed of water correctly but in a different way .. what would happen ?
I don't know which radius question you are talking about.
For arc length you will probably get 1 mark.
