With the adoption of quality points in 1933, students who dropped courses after the course had met as many times as that course carried credit received an LC (Left Class) or an F. In 1943 the rule was changed to giving the LC only if the course had not met as many times as the credit it carried. For students who dropped courses after the course had met more times than the number of credits it carried, students were given the grade of WP if they withdrew passing and WF if failing. If the student was failing the course but had an acceptable excuse approved by the college dean, the grade of WFX was assigned. Drop slips were required to be signed by the professor whose course was being dropped, and the professor assigned the grade at the time of signing the drop slip.
Effective fall 2008, while transcripts continued to show whether a student had withdrawn (W), withdrawn passing (W/P), or withdrawn failing (W/F), the W/F designation no longer counted as a zero in calculation of the grade point average.
In 2011 the new drop policy allowed students to drop full-term courses until the tenth calendar day without penalty and limited students to dropping only four classes after the tenth calendar day during the course of their undergraduate program. From the eleventh until the eighty-fourth calendar day, students who dropped full-term courses received the notation of W, which was not computed in the grade point average. After the eighty-fourth day, no drops were permitted.
