It's possible you could get all the marks. I don't know what the ranges will be.Sir for 3-D,,,,, i wrote (2.5,3) and then m was 0.4
what are your comments and if i loose marks, how many approximately?

hey sirYou'll lose 1 mark.
1 mark will be for just writing 'translation'.
You'll lose 1 mark for b) and at least 1 maybe 2 for c).hey sir
in finding the length MB i got really confused and i wrote 6.8,in the question under it i carried of the sin formula (not the one for the right angled triangles,the other one) and i did get 39,so how many marks will i lose?
sir in the tangent question i drew the tangent at point 2 on b0th the axis and then i calculated the gradient using these values,how much will i lose here ?You'll lose 1 mark for b) and at least 1 maybe 2 for c).
What happens if i get 200/200 for both pp22 and 42?
)
I don't understand.sir in the tangent question i drew the tangent at point 2 on b0th the axis and then i calculated the gradient using these values,how much will i lose here ?
for the tangent question,i drew the tangent at point (2,2) and i then used the line i drew to find the tangent,how much will i lose ?I don't understand.
I don't think you'll get any marks for that question.for the tangent question,i drew the tangent at point (2,2) and i then used the line i drew to find the tangent,how much will i lose ?
Yes.thanks notnek
The pipe question where the water is emptied out into the pool, I got the same answer but left it as 87.4
I lose a mark there?
Sir i am getting 171/200 is it possilble that grade thresholds change this year24 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.
There is only one possible tangent that has a y-intercept of 2.how are u supposed to find the point of the tangent?
