I believe @justinb was referring to the course about page, rather than course content 
The easiest way around this though is to use an HTML component like the one pictured. What I typically recommend is having a staff-only sandbox section containing things like templates that can be modified by users who aren’t HTML-savvy. You can then export the course and use the course import as your starting point, like a course template that contains HTML templates.
This means you can write the about page into a template in the sandbox, and then copy the HTML over to the about page.
Alternatively, if you’ve got more of a support structure for your Tutors to help set up courses, you can give them a form to fill in (like a word doc or Google form) with the necessary details and build the about page for them. That also works!
I’d love to see a much better visual HTML editor in the platform, as the old one is kinda terrible by modern standards, and I’d want to have that visual editor implemented everywhere HTML is used, but unfortunately it’s not there yet.
