To request a swap, click “View/Swap Grids”, in the upper right hand corner. Select 'swap' next to the grid you would like to trade. You have an option here to type in a message and then preview the message. Submitting this will send an anonymous email (from a generic email address) to students assigned to that group letting them know the swap is being requested.
To accept a classmate's request to swap, you may select this option directly from the email you receive, or, go to “My Schedule” to review your swap offers and select this here.
The student who originally requested the swap will receive an automatically generated email letting them know their request was accepted by you. Your new group will then be visible under “My Schedule.” Any other offers you had, will be dropped since they are now invalid
