Our system does not allow students to drop their last class in a semester. This prevents students from leaving the university without completing withdrawal or leave of absence documentation. Our system is set up so that each session (8 week 1, 8 week 2, Summer I, etc.) is viewed separately, preventing the last class from being dropped during these sessions. However, withdrawal and leave of absence documentation are only needed when the last class of a long semester (Fall or Spring) is dropped.
