3. So, how did people do?

Well done, did you get an A* in maths then?

I got 100 UMS as well. Now I'm relaxed with C4

Well done to you too!
Yeah I got 583/600, did you not do C4 this year??

No, I took C3 a year early. I haven't started Year 13 yet. Now I need 80 UMS in C4 and 14 UMS in my applied module to get an A*

btw, 583 is a ridiculous score. You averaged 97 UMS over six modules. I've already dropped 14 UMS in Maths, so the highest I can get is 586.

Cheers mate.
10. Got 100UMS in this, my only 100UMS exam, going to frame the damn paper in my room at uni! Only got 96UMS in C4 :'( jk, hope you all did well too! I was too lucky in C4, realised my grave mistake on that Ae^k question and re did it, saved me the A* right there

In Year 12 and this was supposed to be the hardest paper. Like you, it was my only 100 UMS.
12. 100UMS in C3
13. hi does anyone have the unofficial markscheme or paper, for the 2016 ocr(non mei) c3 paper, would be much appreciated

sinB(1/cosB)^2 = 27cosB(1/sinB)^2
rearranging (sinB/cosB)^3 = 27 so tanB=3
Tan^3(B)=27
Also has two other solutions
27=(a+bi)^3=a^3+3a^2(bi)+3a(bi)^ 2+(bi)^3
0=3a^2b-b^3=b(3a^2-b^2)
=> b=0 OR 3a^2=b^2, using the latter
27=a^3-3ab^2=a(a^2-3b^2)
27=a(a^2-3(3a^2))
-27/8=a^3
a=-3/2
b^2=3a^2
b^2=3(-3/2)^2
b=+or-3sqrt(3)/2
Tan(B)=-3/2+or-(3sqrt(3)/2)i as well 😎
