During the summer terms, courses start and end at different times throughout the term. Students may add or drop courses via the MyISU Portal in accordance with the class length (see schedule below). After those dates, schedule changes must be processed in the Office of Registration and Records. You must obtain advisor approval before processing schedule changes.
Courses may be added according to the schedule below. Instructor's signature is required before
the last day to add, only if the class is full.
Courses may be dropped and will be refunded according to the schedule below. If you are dropping all of your classes, you must follow the withdrawal instructions below.
You will be charged a $10.00 drop/add fee for each completed transaction beginning on May 4 for Summer I and on July 5 for Summer II. Students adding and dropping classes in the same transaction for the same number of credit hours within a session (same class start/end dates) will not be charged or refunded credit hour fees. Students adding or dropping classes with different start/end dates will be charged the credit hour fee for the classes added and provided a refund according to the refund schedule below. A $30.00 late registration fee will be assessed if you register for a regularly scheduled class on or after the beginning day of class or if you register for a specially arranged class after the beginning day of that class. You must have permission of the instructor, advisor, and academic dean.
If dropping all classes for Summer I or Summer II, you must withdraw for the term. To initiate the withdrawal process, contact:
