Thanks!!! What did u get on that one??
I think I got (-3, -2)
2. (Original post by mrpaper)
Wasn't the probability tree 0.8 x 0.95? Some people are saying 0.8 and 0.04?
Can someone remind me what Q18 was?
3. Question 7, about the girl (Kirsty I think her name was) who wanted to paint varnish on her floor but didn't know if she had enough, was the answer that she didn't had enough? Because I worked it out to her having 50m^2 of floor to cover, which meant she needed 10 litres of varnish (I think?) as 1l covered 5m^2. But she only had 7.5l as she had three tins of 2.5l so she would have needed another tin to cover the floor. Was this correct?
4. (Original post by Nooooooooo)
Would I get the marks if I factorised it? For the envelope question?
nooooooooooooooooooooooooooooooo oooooooooooooooooooooooooooooooo
5. (Original post by Lewis__F)
On the right side of the triangle not the actual base of the triangle though right?
Yes it was the side most on the right( which was a nearly horizontal line) to the tangent (which was 69*)
6. (Original post by Chamathil)
I'm pretty sure it is 0.76.
It asked for the probability of it not raining and the match not being cancelled.
7. (Original post by #1Mathlete)

ok thanks, I hope so
8. Anyone know what grade they think 80/100 will be?

Yes, in total she would need 4 tins, however you didn't need to state that.

Anyone know what grade they think 80/100 will be?
High A or borderline A*
Taking in account how easy the exam was I'd say Solid A however with the calculator exam you can push it up to an A* if u do it good
14. (Original post by mrpaper)
Yeah, you had to do 1 - 4 = -3 and 2.5 - 4.5 = -2
(-3, -2)
yass i got that !!!
15. How many marks was the question of x^2=4(x-3)^2 Which the answer was x=2, x=6 ???
16. (Original post by Aol1)
Anyone know what grade they think 80/100 will be?
Last June was 79 for A* but in November it was 83, so you're high A if not A*
