All engineering curricula contain carefully integrated sequences of courses that must be taken in the proper order. It is generally advisable for the student to follow the program as shown in the Programs of Study chapter later in this section. When necessary, a student may modify his or her program to take from 12 to 21 credits in any term. No modification beyond these limits may be made without the approval of the associate dean for academic affairs. Before making any changes, the student should look ahead and assess the possible effects on future scheduling of courses.
