If you are currently not enrolled you should head over to CPE to enroll in the course.
If you are trying to enroll in this course and the capacity has been reached you should make sure you are on the waitlist. The chances that you will get into the class are higher, but do realize that there is a high possibility that this will not be the case. You should, however, begin the programming assignments and complete them in the event that you are enrolled so you do not become overwhelmed with subsequent homework assignments and exams.
If the waitlist is full then it is unlikely that you will be able to get a seat in the course.
