Totally agree here. I visited the page and scrolled through it to see what it was all about and saw a bunch of pull quotes and couldn't work out what I was looking at. It just looks like a light magazine article or brochure until you either click on the hamburger menu to see a full table of contents or scroll to the very bottom to see the table of contents there.

This really needs some design improvements if they want people to read through to the actual lessons. Most people are going to drop off after scrolling through that landing page.
