TOTAL COURSE RESULTS

Okay, this is what you really want to know.  Here are the scores for the final exam, ARS, and the overall sum total for the entire course.  I will enter these scores in SPIRE on Monday after Christmas.

Scores and grades:  2011_Scoresheet

The total score is:  (Fin) + (MT 1,2,3) + (ARS) – (lowest of MT or ARS)

The grade distribution was pretty good – alot of A’s.

I calculated the ARS score (82 possible) by dropping the lowest 15% of responses (maximum score of 70), then converting that score to a scale of 100 (ie: scores of 70 or more earned a 100 on ARS).

I then replaced your lowest midterm score with your ARS score (if it was higher).

Goals: Rationalize LigExch products using mechanisms (SN1 and SN2)
Predict relative rates of ligand exchange wrt CFSE, ion radius, charge, coordination number
