No, not at the moment.

The courses are available as a download only, there is not a streamable option.

If you only have an iPad you need to use either the Files App or the free Documents App to download and have enough space on your device

But there is one exception.

If you open the download links in the Safari browser on an iPad, Safari will give you an option to View or Download, if you click View, you can watch the videos without downloading.
