You may lose a mark for 1743.8 (I would guess you won't) but you will definitely lose a mark for 87.4 because the question told you how to round.sir in the speed question if we wrote.. 1743.8 will they minus a mark? and if we write 87.4?

No. It was one of the hardest IGCSE exams I've seen.the paper was easy right? do u agree with me notneck?
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.

You don't believe me so look here: http://en.wikipedia.org/wiki/Rotation_matrix under 'common rotations'.question 2)a)iii) is wrong its clockwise not anti-clockwise
Do you think all IGCSE exams are easy? Which paper 4 was harder than this?it really was not! i really wonder... why ppl thought it was difficult
So the only reason you thought it was easy is because you're very good at maths. Try to understand that most people in the world don't share your ability.ah yes if ur comparing it with other papers then yes it was!
I have no idea.notnek do u think a 199/200 would be a world ranking??
2 out of 9 isn't there like Ecf for this type of questionsAt least 2 maybe 3.
Maybe. I don't make the mark scheme.2 out of 9 isn't there like Ecf for this type of questions
Isn't that a bit harsh?
Yes, there's a chance.I know you're not going to predict anything, but do you think there is any chance the curve for A* will be 165? Like any chance?
Look at P_1, P_2, P_3,... The bottom left corner of the triangle tells you the position of that triangle e.g. P_3 is the bottom left corner of the 3rd triangle.Sir, no offense but ur last answer seems wrong because answer was something like 19.56
meaning completely 19 triangles can fit in.. that 0.56 is the space left after the last triangle
so
Pn-1 ==> 18
n= 19
i may be wrong
