sentences:  The general structure of a course at IDC is a set of lectures designed to provide a theoretical introduction to the subject, followed by design exercises that encourage students to apply theoretical knowledge to practical problems of their choice.Most courses in IDC run between 2 and 3 weeks in duration, with one or two courses running the full duration of a semester.The advantage of the short course length is that students take only one course at a time, and are fully immersed in it for that time period of learning through lectures and hands-on project work.
