Students are expected to spend about three to six hours a week on their project.
Graduate Courses Open to Undergraduates
A limited number of graduate courses are open to undergraduate students who have maintained a GPA of 3.5 or better in computer science, subject to permission of the director of undergraduate studies. These may be substituted for undergraduate elective credit, or reserved for graduate credit if the student is pursuing the accelerated master's program. Consult the department's website for details.
