# Add/Drop The add/drop period lasts 2 weeks from the beginning of the term. Courses dropped within this period will not appear on the students’ transcript. Students may not withdraw from a course after 2/3 of the course is complete. If the withdrawal occurs after the add/drop period, the course will be listed on the student’s transcript with a “W”. Students are not permitted to change their course registration after the add/drop deadline. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
