A student may choose to withdraw from any number of courses before the semester begins and through each course’s midterm (check each course in myUK for specific dates). Depending on the situation withdrawing may still result in tuition charges, a 'W' on the student's transcript, or even compromise program admission status. For this reason, it is always recommended to discuss with your advisor prior to dropping courses.
UK has a variety of resources designed to help students who might be struggling personally or academically that could help turn a semester around instead of needing to withdraw. These include academic advising and tutoring, mental health counseling, support for first generation, veteran, and LGBTQ+ students, and more.
