Which is ridiculously late. I can't believe we have to wait till August 25th.

Ugh I know there's so much anticipation. I'd so much rather receive my results and have an amazing summer, instead of having your conscience wondering if you did well all summer :frown:.

So true, you have to just forget about it. The results probs won't come through anyway because my inbox is full.lol.
Sorry to be a pain but does anyone have the paper as I cannot remember the Q's lol?
Does anyone remember the functions question equations?

f(X) was 2x-5, not 2x-3, so f(4) = 3

11 d) I got k= 65/6

12 b) I got 9

Are these both wrong?
So f(x) = 2x-5, what was g(x)?

X^2 - 10?

65/6 should change to 11 to the nearest whole number and it was 5 for 12b because you do 9 minus 4 which is 5

Ahh, think I got 98 then 😕
how do you know if the probability question was with or without replacement. It just said she took two coins from the bag. It never specified replacement or not?

Because if you take 2 coins from the bag then that is a single action, otherwise it would have stated she took a coin, replaced it, then too another. It was supposed to be implied

What do you think the grade boundaries will be?

Not a clue. I think this paper was quite easy but the first was harder so maybe the boundaries will go up by 3 or 4 for each x
