| please realize that if you are taking   |
| one course which is offered at only one |
| time on a given day, and another which  |
| is offered at all times on that day,    |
| the second class will be arranged as to |
| afford maximum inconvenience to the     |
| student. For example, if you happen to  |
| work on campus, you will have 1-2 hours |
| between classes. If you commute, there  |
| will be a minimum of 6 hours between    |
\ the two classes.                        /
