Preference Selection

The Preference Selection tool is an online system for students to rank their preferences for the timing of their discussion section for lecture courses and/or the time of their laboratory section for laboratory classes. Seats are distributed to students through a lottery and are placed directly on the student’s schedule. 

Many chemistry courses and labs use Preference Selection. To see if a course uses Preference Selection, look at the course description in Yale Course Search (YCS). Information and links for Preference Selection sites are available directly in online course selection (OCS). Students can also view Preference Selection information, including open and close days and times, on the University Registrar’s Office Preference Selection page

When a student adds any course with a discussion/lab section that has online sign-up, a window will open to inform them when the section sign-up will become available. If this course uses Preference Selection, the pop-up window will also include the dates it will start and end and a link to the Preference Selection site. Students can also access the site from the course description in YCS or OCS. 

If the Preference Selection site is open when one adds the course to their schedule worksheet, they can click on the link and go directly into the site to rank their selections. Specific instructions for doing this are within the site itself. Please email Chemistry DUS with any further questions or concerns. 

The assigned discussion/lab section will be uploaded to the student’s worksheet, when the Preference Selection period ends. Once general discussion/lab section sign-up opens to all students, they can change to a different section, be waitlisted, or drop the course completely from their worksheet.
