    Exam score

    What score do I need to get in my final exam, in order to pass my course?

    I got:
    55% for a test worth 15% of my final grade.
    48% for a test worth 20% or my final grade.
    65% for a test worth 25% of my final grade.
    and the exam I'll be doing is worth 40% of my final grade.

    What is the least percentage I need to get in my exam in order to pass the course?

    What is the threshold for passing?

    You can work out what you have already by \displaystyle \Sigma (xy) where x is the grade you obtained for that test and y is how much of the final grade the equivalent test is worth. \displaystyle \Sigma means the sum of so you add them once multiplied. x and y should be expressed as decimals.

    Using your first result as an example: 0.55 \cdot 0.15 = 0.0825 = 8.25\%


    Spoiler:

    The sum you need to do is
    x_1y_1 + x_2y_2 + x_3y_3 + x_4y_4 = 0.5

    You are given all of those values except for x_4 so solve for that

    What a question! How can the answer to this question possibly be relevant to your exam preparation!?

    I suggest you worry more about things like doing your best and less about things like what the hypothetical bare minimum is that you need to scrape a pass. You will probably do much better as a consequence.
