The midterms will be returned no earlier than class time tomorrow.

43 % of the class have an A or B.
I was hoping for fewer Ds and Fs.

Even an F, combined with a very concentrated effort, can
still achieve a satisfactory grade if you do well in
project and final.

Please check

for the solutions to the midterm. 

I put some nice movies into

midterm-answers-1205-w02.PDF 
midterm-answers-1205-w02.ppt 

Watch those slides on a COLOR MONITOR and see how the answers
unfold in the front of your eyes. Your brain will do the work
quite effortlessly if you just feed it the right colors and arrows.
