what did people get for the last question????
2.5
5. Re: Maths exam IGCSE - HIGHER TIER - PAPER 3H AND PAPER 4H POST DISCUSSION.
I didnt know how to do the Triangle one Can anybody explain how to get DC and AC??

Your probability answer is wrong; it's not 0.75. How did you get 0.75?
its 0.75
its bill then bill
bill joe bill
or joe bill bill

cosine rule
and the rules of lines

could you give more details??

umm dont remember the question well but its suppose to be like:
ac squared=12 squared+6 squared- (2*12*6*cos28)
for dc it should be 12*7=(6+dc)dc... iam not sure for dc
10. Re: Maths exam IGCSE - HIGHER TIER - PAPER 3H AND PAPER 4H POST DISCUSSION.

Cant wait to see if I get my first A*.(probably my only)

how long before the paper and solutions come out?
19th may. thats what some guy said in the previous pages.
14. Re: Maths exam IGCSE - HIGHER TIER - PAPER 3H AND PAPER 4H POST DISCUSSION.
For the factorise out one, Did anyone else get Y^2 - 2y - 35, think it may have been + 2y and ivebeen an idiiot
15. Re: Maths exam IGCSE - HIGHER TIER - PAPER 3H AND PAPER 4H POST DISCUSSION.
I got -2y as well.

I got exactly the same answers as you, fingers crossed they're all correct!
17. Re: Maths exam IGCSE - HIGHER TIER - PAPER 3H AND PAPER 4H POST DISCUSSION.
So I'm taking that most people found this paper a lot easier? Grade boundaries wouldn't just shoot up would they?

for 3C, i wrote 13:30 and 16:30. u think i,d get any marks for that?

I think it'd depend on the graph you drew.

Yes, they usually have a range of answers which they will give marks for. Especially if you've used the graph (and it looks like you have to them too). Personally I got 13:25 and 16:30 I think.
