Grades Updated

29 12 2009

Grades are loaded on OWL and SPIRE.

There were alot of good grades!  I went as low as 68.5% to give “C”, in order to be sure than anybody on that C/C- boundary got the benefit of the doubt.

Points came from:

1) exams + blog (70% of points): 420 points (100 per MT, 120 for final; up to 5 extra points added for blog participation).

The lowest MT was replaced by a better final (on a percentage basis!) as shown by the extra column of numbers in the OWL Gradebook.

2) Lab (17% of points) 100 points

3) OWL (10% of points) 60 points.

4) PRS (3% of points) 20 points.

*******************************

Letter grades have been placed on SPIRE

Letter grade regions will be pretty close to traditional percentages, but this is key:  you need a passinge exam average to pass the class. I accepted an exam average as passing if it were greater than 54%.



Did the final replace a MT?

24 12 2009

Yes.  Probably.

The final exam is worth 120 points.  Each MT is only worth 100 points.  Therefore, the replacement of a low MT by a Final is on a percentage basis.

For example, your lowest MT = 55, your final = 90.  You do not get a 90 for that low MT.  Instead, you get (100*90/120 = 75).  So a “75″ replaces the “55″.  Please double check your calculation of percentages – before you write to ask about this!

Merry Christmas!



Final Exam – Friday, Dec. 18

11 12 2009

Final Exam – Friday, December 18

4:00 – 6:30 PM      Thompson Hall 102/104

Cumulative exam, 41 questions (each question is worth 3.0000000 points for a total of 120 points.  so one Q could lead to bonus points)

Final and Answers

The exam was scaled by adding 6 points to every exam, as two questions were a little weird.  Absolutely correct, mind you, but they tested weirdly.  So the resulting exam average was 82.3 points (27.4 Q correct).

Practice exam (From Prof. Adams, 2008)

University Exam Policy

For extraordinary reasons, I can offer a final exam at a time other than the normal time – contact me ASAP for more information.  But please make sure that your reason is a good one (see the Univ. Exam. Policy).
