21-241: Final Wrap-Up

Well, we have reached the end of the semester. I've turned in the final grades, and you can all see your final exam grades on Blackboard. I think I've got the Blackboard "Cumulative Average" computing everything correctly (I use a separate spreadsheet to calculate and assign grades). (A few students have discussed issues with some of their homework assignments this semester. I believe I've resolved those issues, but have not changed the Blackboard grades to reflect that.)

The grade cutoffs for the final exam were:

A cutoff - 80
B cutoff - 70
C cutoff - 60
D cutoff - 40

and the grade cutoffs for cumulative averages were:

A cutoff - 82.37
B cutoff - 69.47
C cutoff - 56.58
D cutoff - 40.26

I enjoyed working with you all this semester, and I hope you have a great summer.

21-241: More solutions

I've posted the solutions to the review problems from section 6.3 on the Blackboard site - on the Assignments page with the other solutions.

I will be available in my office tomorrow (Friday) between 11:30 and 1:00 to field any last minute questions, are return any homework that anyone would like to pick up.

21-241: Grade Cutoffs

I've heard from a few of you asking how to interpret your "Cumulative Average" from the Blackboard gradebook. As you are likely aware, the grade cutoffs for your final averages will depend on the grade cutoffs for each assignment. I average these cutoffs (the same way I compute your averages) to get the cutoffs for final averages.

To interpret your "cumulative average" you should use the following cutoffs, based on the mid-terms and homework to date.

A cutoff - 83.21
B cutoff - 69.29
C cutoff - 55.36
D cutoff - 40.36

The final cutoffs will depend on the grade cutoffs for the final exam. The final cutoffs may be above or below these cutoffs, but probably not by too much.

21-241: Final Exam

I've posted the review page for the final exam. The final will be Friday, May 7 at 5:30pm in UC McConomy.

I'll make solutions available for the review problems from sections 5.6 and 6.3, as these topics were not covered on a regular homework assignment.
