Can I download my course to watch it offline?

Generally, yes. For most of my courses, on the video lessons page, if you scroll down to the Resources section, you'll find a link to a ZIP file that will contain all of the videos in MP4 format that you can download to watch offline.

Even if that particular course doesn't have a ZIP file, you can download pretty much any video on the website that you want. Just click to play it in your browser, and then once the video starts playing, right-click on the video window and select "Save video as..."

This method works in Google Chrome, Microsoft Edge, and Firefox.
