This app is a powerful app to help you create a calendar for your lecture schedules. It's very easy to use as you don't need to do anything but install the extension and run it. It will look for all the lectures from other sections and will convert them to a downloadable file that you can import to your calendar app. There are different options for how to view them and select the ones you want. Once you hit "Download" it will start to download all the lectures that you have selected.
