While you can view the courses for which you are currently registered in the Current Schedule section of the Add/Drop Worksheet, you will not be able to access the Worksheet when the registration window has passed.
You can still view your schedule by going to the Registration Menu. Select Student Schedule by Day and Time or Student Detail Schedule. Each of these options will show your schedule in different formats. In addition you can view your schedule from the Academic Transcript under the Courses in Progress section.
