Online/Hybrid class students must access the lectures via the "online student login" button (there will be no login button for lectures 1 - 3, the online login button will be activated for lecture #4)
To download the lectures, ctrl. click (Mac) or right click (Windows) on the "download" link. You will get an .mp4 file that you should be able to watch on your computer at any time. Warning, the mp4 files are large (ca. 40 - 45 MB), an entire course worth of files will take a lot of disk space, ca. 1.5 - 2GB! That is about as much space as a movie. You may have to make a choice of what to put on your computer, a semester of o-chem or one of your favorite movies :)
