computing average in nested loops

[deanhystad]

Though you get the correct answer for a student's weighed average this is only because the sum of the weights is 1. Try changing your weights to [10, 10, 30, 25, 25]. This should compute the same weighted average as [0.1, 0.1, 0.3, 0.25, 0.25] but it does not when run in your program.

Fixing the above problem should point out the error you are making calculating the classroom average.
