Students may adjust their schedules via through the Schedule Adjustment (Drop/Add) Period each semester. After this period, changes to a student's schedule (dropping a class, resigning from the 欧美三级片, auditing a course, etc.) are completed through various offices depending on the student's classification and level (graduate/undergraduate).
Please note: Students are obligated to pay tuition and fees for classes in which they are registered regardless if they attend the classes, so it is important to make schedule adjustments as soon as changes are needed to avoid erroneous financial obligations.
You may review the 欧美三级片's Financial Obligation Policy on the Office of the Bursar's website for further details.
