Thank you so much!!! Only one I got wrong!! Some I cant remember, feeling quite confident, fingers crossed I get over 90 Thankyou!!!

Hoho ^.^

I've got the same answer for all but the triangular prism one (I somehow forgot to half the area to get the area of the triangle >.<)

Oh no...I lost far too many marks. I need like 95 to get an A* now. Thankfully it's a mock!

Got around 90 marks for this. Thanks a lot Mr M. By the way in your opinion do you think this paper was easier than past papers?

Does anyone remember what the actual question for the inverse proportion was?

Does anyone have the link to the questions? I spent so much time tracing the dragon/monster but then the invigilator took away the tracing paper >.<

Also how do you workout the probability one

LOL! I did that too And I've forgotten all the questions so I'm not sure if I got it right or not now..woops.

I can't really remember the last paper as I have done dozens of them over the years. It seemed pretty straightforward though.

y is directly proportional to the square of x.

When x=3 y=36

Find y when x=5

(Original post by dansag)
Also how do you workout the probability one

0.7 x 0.6 + 0.7 x 0.4 + 0.3 x 0.4

Guys!! What should we revise for tomorrow?

What was the standard form question?

Umm
'' 16. Surface area of monsters

10800 (3 marks)''

Do you mean 1800? Because I remember the small one was 300. Please tell me I'm right!

Thanks so much!

Can you post question 20 a on the fractions please? I just want to confirm ☺
