What do you think an A and a B would be?
If they lower A* to 39 A will be 34 and B 26 (but that only happened in june 2012 when the spec was new so i doubt it will happen again)
If A* is 45 A will be 37 and B 29 (if they decide to be mean and think the paper was fine)
If A* is 42, A will be 36 and B 28 (this is something that is likely to happen if the overall statistics show low grades of students then they will have to lower the grade boundaries)
If A* is above 45 we all are f***ed
2. The question was:

=0.67%

Wrong 0.7% because 0.666 rounds to 0.7 not 0.6
I personally think that this year, A* will be 41/60. Here are my reasons:

In June 2012, A* was 39/60. Some people may say that it was because it was a new spec. However, in June 2014, A* was 44.
Given that today's exam was possibly the hardest ever in the series, I think A* being 41/60 a pretty good prediction
What would you say a B grade would be?

I swear that's right?
That was right!
6. Why was is a scatter graph?? :s
7. (Original post by _Xenon_)
i mean what grade roughly looking at other years
It's been 20 for a C the last two years, 24 the year before that. Could be a C, could be a D.

What would 32/60 be?
i would gess a 'B' but im not sure?

To allow you to look for correlation between two continuous variables.

Lets pray the grade boundaries are low considering the paper was really hard!

Firstly, June 2012 it was not 39. It was 26 (Yes, I know!!)
Secondly, absolutely no way that this year's paper is the hardest ever. June 2012 is nasty, and January 2013 was an absolute *******.
41 is really low given the last 3 years have been 45, 44 and 47
I can assure you that in June 2012, A* was 39/60.

I put because it is catagoric data but that is probably wrong

16. (Original post by Cirsium)
Umm if you put 0.66 then you did x100 or else you'd have got 0.0066! All the people saying 67% are wrong
oops made a mistake in writing that, I got 0.0067 and didn't times by 100
17. (Original post by Cirsium)
It's been 20 for a C the last two years, 24 the year before that. Could be a C, could be a D.
If I get As in B2 & B3 what grade am I looking at roughly considering I got 38/50 in my biology ISA, got roughly 22 marks on this exam. :/

Categoric data is like red, blue, white... You can't plot it on a scatter diagram.
