Do all courses run for a set term or are there some that I can schedule on my own time (open entrance or exit)? ANSWER: All courses follow the Virginia Tech academic calendar. Students can take courses during the fall, spring, or summer terms. Courses have scheduled deadlines, scheduled exams, and online meeting times that must be followed.
