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 six discussion quizzes, the first three labs, and exams 1 and 2. Your overall score so far will be available on Blackboard. The overall scores so far will be updated after exam 3.

The average overall score so far, after exam 1, is 704/1000 = 70.4% (shown as the vertical line); the dashed lines standard deviations from the average; the high score was 967/1000 = 96.7%; 783 overall scores are shown. Last updated Tuesday, October 30, 2018 11:59:00.
