Physics 123, Sec. 1, Spring 2008

Exam 1 is now graded and will be turned back to you on Monday, May 19. The average on the multiple-choice exam was 75% and the average on the homework-style exam was 80%, about like previous semesters and terms. I made a mistake in the numbers on Problem 4 on the homework-style part which made the problem somewhat confusing for some people. Because of this error I gave generous partial credit. If you want you can do this problem again using the corrected version. If you choose to do so I will replace your old score on this problem with the new one, but you can't do the new one and then take the larger of the two scores. If you ask me to grade the new problem I will replace your old score.
