Berkeley Schedule Exporter for chrome from Ziyao Zhang
The Berkeley Schedule Exporter allows you to export your Berkeley class schedule in an ics file. This can be imported into Google Calendar, where classes are automatically grouped by week and day.
To start using the app, you first need to log in using your CalCentral username and password. This will give you access to your CalCentral account. Next, you need to select the classes that you want to export. This can be done by selecting Current Schedule or Shopping Cart. You can also select the courses you want to export by searching for them.
After that, you need to click on the extension icon in the upper right Chrome menu. This will bring up the Exporter.
