What are the best free text-based courses you know?

Apologies if this is the wrong place to ask, although if you could point me in the right direction I'd be grateful.

I have a concept for a method of learning which is completely text-based, don't want to say too much about it right now but I've been working on a website for it and would now like to test it out to see how effective it really is. Best way of doing it is on a subject I know next to nothing about.

Preferably something which is split into a table of contents and each section is split into paragraphs.

Thanks!
