4. 69 in C3 and 64 on C4, think that could scrape me an A*?
Absolutely gutted after C4 today, my entire paper was just smothered in stupid mistakes

no as in 4 coordinates other than the origin? - on that note i didnt knwo the origin was one
I'm unsure about the origin because if the origin would also make dy/dx infinite as the denominator is zero?

the origin is not one of the coordinates i dont think - but i do think there are 2 other ones to the ones everyone has on their predicted answers/markschemes
7. That paper was goddamned easy
8. A few people have asked this I think but no response. How many marks am I looking to lose if I used degrees instead of radians in the differential equation question? It didn't specify which to use so I figured degrees, but it seems everyone else went radians

Will 70/75 on C3 and 69/75 on C4 be an A*?
Are you being serious?

13. i got around 49 marks without method mars
i got about 60-62 in s1
i got about 60 in C3
C2 i got around 65
I got 89/100 in C1
i got 67/100 in D1
would i be able to get an A
14. I've emailed edexcel as integrating 3^x is not explained in the textbook so they shouldn't really ask a question on it!
15. Wow according to the mark scheme floating about I got about 64-68. Yay
16. (Original post by xKay)

People who are posting your UMS asking what grade it is, go to this site http://umstools.sourceforge.net/demo...tor&target=gce and chose mathematics 6 unit specification!
Got mine wrong, said I wouldn't get A* even though my C3 and C4 average to above 90. Decent otherwise.
19. Would an A in maths be considered bad, looking back Ive dropped around 7 marks give or take,and I'm trying to reassure my self that an A is still good, but I'm still not really satisfied :/
20. C1: 87 ums
C2: 83 ums
C3:62/75
C4: 52/75
D1: 65/75
S1: 74 ums
Anyone have any idea what this would be? thanks
