We will use this time to go over the results of Exam III, and review for the final exam.
Final exams for Winter Quarter begin on Wednesday, March 18. The times the Chemistry 140 final will be offered are indicated below; the exams will be held in the classrooms indicated. You must take your exam at the designated time unless you have made arrangements to take it earlier. Students in the day section are welcome to join the evening class on Wednesday.

Final exams will not be available for pick up until after all of them have been graded, which will likely not be before Friday noon, March 20. If you would like to have your exam mailed to you leave a stamped, addressed envelope with me at the time of your final. Otherwise, the exams can be picked up at the beginning of Spring Quarter.
If you would like to have me e–mail your exam and final grades to you, send me an e–mail requesting your grade prior to 11 AM on Friday, March 20. Do note, I will not be responding to e–mails during spring break! Yes, faculty take a break too!
Have a great spring break, and I’ll see you on March 30.
