*UPDATE 2.0*: WatCal now utilizes UWaterloo's Open Data API instead of UWFlow's and is more flexible. Better user experience. It is also no longer limited to only Fall 2016.
Simply head over to Course Selection -> view my class enrollment results -> click on the term that you're interested to export your schedule from (e.g. Fall 2016). Please wait about 3 to 5 seconds for the `Download Schedule` link to appear under `Successful Course Enrollment` and you'll be able to download the Calendar file through that link.
You will be able to export your entire University of Waterloo class schedule, excluding Tests (as the venue is not updated yet), in one click. You can then import the generated iCalendar (.ics) file into many popular calendar applications, including Outlook, OS X Calendar, and Google Calendar. Note that your calendar's timezone should be set to America/Toronto (UTC-05:00) in order for the schedule to reflect the correct time.

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
