Another question i just remembered - the graph.
The cumulative frequencies were in descending order:
4
11
32
53
71
78
80
The first two might be wrong, cant really remember.
The number of people over 85kg was 80-62=18
The IQ range was 83-63=20

the first one which has 3 mark

I think I used sin but I can't remember exactly sorry

for the sine triangle question am i right in saying that you had to find out the angle first and then use the formula , it was the 3 marker near the beginning

I'm pretty sure the simultaneous equations was Q13. The two answers were y=7 and x=-3 I think or the other way around

Yes.
Can anyone remember the question which was algebraic, we had to rearrange something to get t.
t was equal to m+1/m-2 i think, cant quite remember.

An A is most likely lower than that, as an A* would be about 79-80% on this paper.

and by the way my teacher said that paper3h is always the hard paper and that paper4h is the nicer one.

You were given 4.5cm which you have to convert to MM via the multiplication of 10, giving you 45cm.
The upper bound value of 45 is 45.5, hence you have 45.5MM
Divide this by your MM value, which was 3. This needs to be a lower bound to produce a maximum value and so you should divide by 2.5MM ( question stated 3MM to nearest MILIMETRE).
This would have given you 18

Nope, it was a cube, and it was 4.5cm to the nearest 0.5cm, not 0.1cm. Therefore upper bound is 4.75.

Also, as it was a cube it's 4.75 ^ 3 / volume of the spheres, which lower bound was 4/3 * pi * 0.25cm^3

You've got it very wrong, I know this may be zillionth time someone's told you this as there are 17 pages, but just wanted to point it out

for the circle theorems it was a 4 mark question. I got a final answer of 48, but that's incorrect because people are saying it was 63. Would I get 2/4 marks because I worked out the 105 then added the other angle to it and took that total from 180. But I didn't add 15 on to the 48.

what was the answer to the probability one igot something like 25 something out of 500 something
i did the following combinations
2 2 2
1 2 3
2 3 1
3 2 1

most likely 2 marks

I don't know, but don't bank on it. I would expect a nasty surds question, a nasty indices question, a nasty simplification question, a nasty inequalities q... and many more!
