Overall scores so far. As detailed here, course grades are assigned based on the distribution overall scores at the end of the course. Based on past experience, it is likely that the average overall score will correspond to a grade in the C+ range. The overall score so far is not a running total of the points earned in the course. Rather, it is an estimate of what your final score, out of 1000 points, would be if you continued to perform at the same level. This means that if you have received perfect scores on all work so far, your overall score so far would be 1000, and if you have received 50% scores on all work so far, your overall score so far would be 500.

Here is the distribution of overall course scores so far, on a 1000-point scale. These scores are based on lecture quizzes, the first nine discussion quizzes, the first six labs, and exams 1, 2, and 3. Your overall score so far will be available on Blackboard. There will be no further updates to the overall score so far

Overall score so far: The average overall score so far, after exam 3, is 725./1000 = 72.5% (shown as the vertical line); the dashed lines mark 1 and 2 standard deviations from the average; the high score was 975/1000 = 97.5%; 602 overall scores are shown.
