that's still high for me lol.
I wonder if a B has ever been in the 50s...
I'll give you the grade boundaries for the past 5 years except 2006 which I can't find. All of these are out of 130 and are not percentages

2010
A1:108
A2:97
B:81
C:65

2009
A1:106
A2:93
B:77
C:62

2008
A1:113
A2:101
B:84
C:67

2007
A1:113
A2:101
B:83
C:65

2005
A1:111
A2:98
B:80
C:63

60% is 78/130, so yes in 2009 it was in the high high 50s.

In paper 2, Question 1a I got the co-ordinates of B wrong but did all rest correctly, would I just lose 1 mark?

It isn't 3x^-4 it would be (1/3)(x^-4) since the 3 was on the bottom.
Aha, the penny has finally dropped.
38/40; bah!

Yes I think so.

As long as you don't get cos theta to be >:0, then yes!

But don't you think 10 marks is a bit generous for doing that?
But that was all that it was asking you for.

Did anyone think for the last question that there were a lot of marks for it? I was sitting there wondering where the hell these 9 marks were going to be given.
YES! I was thinking that as well. I only did about 3 different things, if that!

I actually thought most of the paper seemed that way as well - like the 10 mark integration question and that other 7 mark one. Hopefully it means it will be easier to pick up marks, right? Or am I just too optimistic? :P

Was the size of angle BDM 40 degrees?

Around that 40.2...

Hi guys!

In the second paper, the answer to question 7 is: p is greater than -23. I asked my maths teacher as soon as I came out of the exam if this was the right answer and she said it was.
But it also can't be 13 or greater. As root13-13 = 0 and you can't have a radius of length 0 units and also root13-14 (or any number greater than 13) will give you a math error on your calculator.

I didn't get the -23 part but I got the p<13 part
13. Re: Higher Maths Post Mortem thread
I may be wrong on the .2, could be .6.

Yes, I didn't think of that. :P

Got tht too atleast I got 1 question right woo
17. Re: Higher Maths Post Mortem thread
40 degrees for angle BDM? Whaaaat? I got 25.6 or something like that.
18. Re: Higher Maths Post Mortem thread
Surely they can't take marks from someone if they got 40.x when the answer should be 40.y?
19. Re: Higher Maths Post Mortem thread
(Original post by soup)
I got .3
I'm sure a rounding difference wont matter.
20. Re: Higher Maths Post Mortem thread
worked it out again, 40.29098639
