    What do I need to get on my final if...?

    Each of the 2 quarters are 40% and the final is 20%.

    I want to get an A, the lowest A is a 93%.

    So for Q3 I got 94.1 %.
    For Q4 I got 91.0% (for now).

    Like I said, I want to get at least a 93%.

    If there is a formula I can use I'd love to know so I can figure out other classes as well.

    Thanks!

    (Its the same for all classes with the 40-40-20 % policy)

    You want a grade x xuch that (94.1+91)\cdot 0.4+0.2x\geq 93 \Longrightarrow 0.2x\geq 93 -74.04\longrightarrow x\geq \frac{18.96}{0.2}=94.8 ...you'll need to do a nice effort.
