For the fall semester, the department will offer two sections each of $3424$ and $4464$ ; three sections of $3434,3444,4434,4444,$ and $4454$; and one section of $3454.$

The normal semester teaching load for a regular faculty member is two sections. $($Once the department head determines the courses, he will assign the faculty he schedules the course times so they will not conflict.$)$

Help the department head determine a teaching schedule that will satisfy faculty teaching preferences to the greatest degree possible.
