NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

My whole life had been destroyed. My 3 answers to a 2 mark Question might not give me an extra mark. I think I'm losing my will to live.

I'll lose it after exams next week :tongue:

-Iffy-

Overall i thought it was a good paper :smile:

though for the teacher and guessing answers question i spent a good 5 minutes wondering if i got Ho and H1 right lol. :s-smilie:

i just about finished it in time and was able to check over it once. Though at the beginning i wasted a bit of time, a wasp had to land on my formula booklet and stay there for a good minute. Had to get the invigilator to remove it *shudders*

I wonder if the grade boundaries are gonna be high for the paper, really hope i get an A.

Any two from

n must be finite
success or failure
independent
probability of success constant

I know I put three in the solutions but you didn't need to

I put down either have the disease or not - two possible outcomes.

Thats the same as success or failure yeh? Hopefully that, along with it being independent, will give me both the marks.

so for the 6 mark normal dist. question i used the value 15.5 instead of 14.5 (got my continuous corrector thingy wrong) but everything else was done in the exact same way.

how many marks would i lose for this question? i know i've lost either 2 or 3 marks, just don't know which lol

Surely NOT - I didn't find it that easy, it was kind of easy, but that is just TOO high, especially after that Q2 fail, surely it shouldn't be that high!

not it wasn't that easy but it was still not hard to warrant such a high grade boundary. I have a feeling they have changed/ are conspiring to give people low UMS this year. The C4 grade boundaries are EXACTLY THE SAME.

This and C4 are both ridiculously high. I found these 2 papers harder than M2 and tha grade boundary is 68/75 for 90 UMS!

We should start a facebook protest!

whilst that may be true with those grade boundaries they aren't testing you on how well you can do the questions but how many silly mistakes you make. Losing just 4 marks which is most cases 2 mistakes (usually 1 method and 1 accuracy each) will cost you 90. This why they should make exams a little harder otherwise things like this happen.
