How to Add and Drop Classes

View these videos to learn how to add and drop classes on Mosaic.

How to Use the Mosaic Student Center

You can drop and add courses on Mosaic by navigating to the ‘Student Center’ tab and following this process. You can search for classes under ‘Search’ on the left under Academics, or you can click the Search for Classes button on the top right of your screen. For details, see the ‘Mosaic Student Center’ video.

How to Search for Classes

On the search page, you can enter the search criteria to narrow down your search. To browse by subject, you can choose the Select Subject button, navigate the list, and click ‘Select’ when you find the right one. You can search by ‘course number’ (e.g. 1A03), but students should ignore the ‘class number’, which is mostly for staff use. When using the ‘Meeting Start Time’ option, ‘greater than or equal to’ means ‘starting at or after’ a certain time. You can use the ‘days of the week’ feature to include or exclude courses with meetings on certain days. For details on advanced searching, see the ‘Finding Classes to Fit Your Schedule’ video.

How to Enrol in a Class

When you have identified a course section in which you would like to enrol, select the radio button beside it and click ‘next’. You’ll have a chance to review the details, before clicking ‘next’ again to add it to the shopping cart. Once the first course is in your shopping cart, you can either continue to search, or move to the next step. When you are ready to ‘check out’, click on the Enrol tab. You’ll see a review of your shopping cart. To confirm, select ‘Proceed to Step 2 of 3’, and click ‘Finish Enrolling’. For details on Adding classes, see the video on ‘Searching for and Adding Courses’.

How to Drop a Class

To drop a course, navigate to the Enrol tab in the Student Center, and select Drop. Select the course you would like to drop, and confirm.
