    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.

    In Year 12 and this was supposed to be the hardest paper. Like you, it was my only 100 UMS.

    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 😎
