Hi, Everyone --
I've posted the key to the final. (Sorry I forgot to do this yesterday.)
We've graded all of them; see summary distribution below.
The mean (79.5) and median (83) on the exam were lower this year than in years past (mean is usually 85-89), so if you found it difficult, you had company (and we feel your pain). The good news if you did not do too well is that this year the exam counts only 40% of the grade and in any case I grade on a curve. I'll be figuring out total grades soon, and will send around histograms, etc. at that time.
Best wishes,
Tom
