It’s very useful to have two DragonNet calendars on your google.calendar: one for your daily class schedule, and another for your homework. This assumes, of course, that your teachers are posting their class homework on myDragonNet.
To get the feed for your homework assignments, go to myDragonNet and select ‘Calendar’, then ‘Export’
Then choose the settings as shown below (make sure that “includes calendar entries” is the ONLY thing selected), and copy the URL at the bottom of the page.
Then go to your google.calendar, and click on the down arrow beside “Other calendars” and select “Add by URL”. Paste that URL into the window.
You can go to the settings for that calendar and change the name after it installs.
This is different than the calendar feed you may have selected previously, which shows only your class schedule. If you haven’t done that (or if you have both your HW and Class Schedule on the same calendar) download another calendar link with THESE settings, and again, copy the URL and paste it into google.calendar.
You can give them separate names and colors in google.calendar so they don’t get in each other’s way.
