- Then click on Register for Classes

- Select the term and continue

- Click on the Enter CRNs tab, then enter the CRN for the class you would like to add, then click Add to Summary

- In the Enter Your Authorization Code pop-up window, input the 6-digit add code provided to you by the instructor, then click Confirm

- To complete your registration for this class (as the class will be "pending" in your Summary screen), click the Submit button in the Summary screen
