You cannot drop a course through MyPlan, but you can drop a course through the Registration page available via MyUW and view your updated schedule in MyPlan.
On the MyUW homepage, scroll down and select the Academics tab.
Select the Registration link highlighted in the image below.
From the registration page, select the boxes to the left of the SLN of the course you are interested in dropping.
Once you have selected the class you wish to drop, scroll to the bottom of the registration page and select Update Schedule. Your schedule should now reflect your dropped courses. Any courses you have not dropped will be reflected under “Your Current Schedule.”
To see your new schedule reflected in MyPlan, navigate back to the MyUW Main Page and select MyPlan under Quick Links.
On the MyPlan homepage, your current schedule will have a purple heading and your new schedule will be visible under the title “Registered.”
To see more details about your updated schedule, you can select your current quarter from the top of the MyPlan homepage. If you are already logged in to MyPlan in another window, you can refresh the page to see your current registered courses.
