    Weighted averages are calculated by multiplying the value by the "weighting" ... with the expectation that the "weighting" adds up to one hundred percent.

    Therefore, your "average" would be:

    (0.50*0.10)+(0.92*0.10)+(0.88*0.20)+(0.50*0.10)+(0.75*0.25)+(0.00*0.25)

    = 0.5555 = 55.5 percent (so far) ... I expect you haven't written the last test yet.

    Which means, by the way, that a perfect score on the last test would only give you an 80 percent for the semester ...

    multiply each percentage by its weight and add so

    9.2

    17.6

    5

    18.75

    0

    = 55.55
