Ah, but we actually can do it.

The 70.76 is already an average of all scores so far.

70.76 will be 90% of the final grade, 0.0 will be 10%.

This is just a weighted average situation with a 9:1 ratio.

Final Score = [(9)(70.76) + (1)(0)] / 10 = 63.68.

You're still passing, but don't skip any more tests! :-)

No offense, Jonathan. I don't want to do the really tough stuff any more: calculus, linear algebra and DE like you do. I never needed any of that beyond calculus with polynomials in my 30+ year career. I have, however, bumped into weighted averages in many forms.05/23/19
