The Summer 2013 wait lists will open up on Friday, March 1st at 12 noon. Students who signed up on wait lists earlier yesterday or today will be deleted from the lists and will have to sign up again on the Summer wait lists tomorrow at 12 noon.
You are strongly advised NOT to register for more than two 3-credit courses in the same Summer term [May-June or July-August]. Each 3-credit summer course requires six in-class hours per week and approximately 18-24 hours outside class per week, for a total of 24-30 hours per week per course.
Taking two 3-credit courses in a Summer term is at least equivalent to taking four 3-credit courses in a Winter Session term. The content and requirements for 6-week summer courses are the same as would be the case if the course were offered in a 13-week winter term. If you are not working and are essentially not doing anything other than taking courses it may be feasible for you to register for ONE 1-credit course in the May/June term if you are also taking two 3-credit courses, but you will be REALLY busy during those six weeks.
The web-delivered courses can often require more time per week than face-to-face on-campus courses [as you may be experiencing this term in 500], so keep that in mind when you select your courses.
