21-260: Exam #3 Roundup

I've taken a look at the statistics for Exam #3, and you can to. The grade cutoffs for Exam #3 will be the standard array: 85 and up is an A, 75-84 a B, 65-74 a C, and 50-64 is a D. Again, I was impressed by the scores on what was a fairly difficult exam.

The page of statistics linked above has data for the whole semester. The grade cutoffs for each assignment are shown, and also for your cumulative average. Your weighted average in the Blackboard site is close to, but not always exactly, the average I have computed for you. In the previous version of Blackboard, these were the same, so I think Blackboard may have changed the way it computes the averages. I haven't been able to figure it out exactly. I'll let you know when (if) I do.

How did u calculate cumulative average? is that something like ( hw * .15 + E1*.2 + E2*.2 + E3*.2)*100/75? or is just average of 3 exams?
