Doubles

Some of you had more than one answer on your scantron, as indicated on the printouts you received today.

After class, I double checked the scantrons of several students, and many of them picked up one or two points. There was a smudge on an incorrect answer, poorly erased, and a true dot on the correct answer.

Interestingly: a few students did not get any points, and in each case, they erased the correct answer, and they bubbled in an incorrect answer! So as they say, if you change your answer on a multiple choice test, make for dang sure that you have a good reason to change it!
