The Inoreader export in the form of HTML Clippings is a premium feature, but you can also combine and share feeds in the form of Inoreader Bundles, which is a free feature. For someone to view your Bundle, they also need to have an Inoreader account (again, a free account works). You can find out more at the Inoreader Bundles page; here's a quick overview step by step:
Make a Bundle
To make a bundle, go to the Preferences (click on your user image in the upper right-hand corner), and then choose Bundles from the Collaboration menu.
You can browse your feeds by folders as you add them to the Bundle, so if you have all your course-related feeds together in a folder, it's easy to add them quickly to the Bundle. (But remember, if you add new feeds to that folder later, you'll need to come back and add them to the Bundle too.)
Share the Bundle
You can then click on the Share icon to get the address for the Bundle which you can share with others. For example, here's the address for the Summer 2020 Blog Fest Bundle:
https://www.inoreader.com/bundle/0014cd640a7d
As you can see, a Bundle URL is not specific to your account, although you are the only one who can edit the bundle. You can share this link and anyone with an Inoreader account will be able to view the Bundle. You have the same different viewing options for a Bundle as for other Inoreader content:
