CityU Timetable Checker

Timetable checker for CityU mates. It reads class information from AIMS and match against your timetable to see if time conflits with sessions occurs.

This extension is for CityU students only, and only works when you are using AIMS.

Browser Support

This is a Chromium-based-browser extension that can be installed on the latest desktop versions of Google Chrome, Vivaldi and Microsoft Edge. (Other Chromium-based browsers may be used, but we do not guarantee it works)

How it works

This extension will read your class schedule when you go to Course Registration > Main Menu for Web Add/Drop > My Detail Schedule.

Then, when you browse the Master Class Schedule and check sections provided by a particular course, you can find out whether conflicts with the section and you current schedule occurs.

The extension will append 3 cells to each row of the table, showing the status and available actions. (Example below)

This extension also provides a wishlist function for you to save the CRNs of the courses you want to register. It can also auto-fill the CRNs in the wishlist to the Add Classes Worksheet in the add/drop interface. (You still need to click "Submit changes" button manually to apply changes)
