Hello,
Prior Term Copy has been run for the Winter 2023 term this morning which means we now would like to have the 1231 term added to the drop down menu on the following Schedule of Classes pages:
https://classes.uwaterloo.ca/under.html
https://classes.uwaterloo.ca/grad.html
Could you please add 1231 to the drop down menu on both these pages?
Once that’s finished can you please place this Jira in the scheduling queue so they can change the wording on both the Grad and Undergrad schedule of classes:
From: Note: Fall 2022 information is PRELIMINARY and subject to change.
To: Note: Winter 2023 information is PRELIMINARY and subject to change.
And also:
From: Term (1219=Fall 2021, 1221=Winter 2022, 1225=Spring 2022, 1229=Fall 2022)
To: Term (1221=Winter 2022, 1225=Spring 2022, 1229=Fall 2022, 1231=Winter 2023)
Thank you so much!
The term being added is handled by the Systems team, the notes being changed on the SoC are done by someone on the scheduling team.
