lol, why do you do that to yourself... please don't starve yourself...
I'll be alright. Last exam anyway. That S1 exam was horrible though.
2. For Q4B, I couldn't find A or prove B so I "claimed" that I found a =8 and b=8 in the previous question (obviously this is wrong)
I then carried this forward to question 4B and tried to work out the value of K and I did all the right steps that I could have worked out K with if I had the right values.
How many marks will I get for this? If any :/

Okay fine I'm prejudice against S1 and have conditioned myself to hate it. Oddly enough I found it the hardest out of all my maths units.
6. Was the area f a circle uniform distribution questions 7^2 pi?

If you got 75/75, why are you thanking people for lowering grade boundaries?

I think you guys had a little of a misunderstanding about the subtleties of this question. You had to find E(R^2), not (E(R))^2.

Because he got 75/75 for the mean of the binomial dist.

Nah mate need 68UMS for an A overall and looks like I'm not getting it. I calculated a strict 57 marks in the exam. lets say minus 3 for that ******* question. Thats 54. Will that make 68UMS?

I don't know anything about grades and grade boundaries, so I can't answer.

It wasn't:/ youre meant to use E(R^2) instead

I made that mistake too

Last year, a C was 53 and a B was 60, but i think most agree this paper was harder
It could very possibly be 68UMS, You have a solid shot
20. how many marks was the P(7<R<10) QUESTION WORTH was it one or two marks?
