Teaching schedule

For some reason this semester I have a teaching schedule that does not agree with my bio-rhythms. I have to teach from 3:30 to 5:30 on Fridays then go to Accra to teach from 6:30 to 8:30 and don't get home until about 9:30. Then I have to teach again at 7:30 am on Monday mornings. I would prefer to have all my classes closer to the middle of the day.
