How to open Sketchup Campus lessons on SU Web/Free?

I’m on a MacBook. I’ve downloaded the Fundamentals course, it won’t open from the Mac so per a 4 year old forum post I tried to open it from the web app. I went to the first unzipped folder, and al lit allows me to open is the Quick Start - Final Park model - no lessons, no info, nothing. What am I doing wrong, and why do I keep having to ask that question when trying to learn this program?

So, the video didn’t show up the first time I was on the page, or at least I didn’t notice it. there’s no general "Here’s how courses work’ notice anywhere, even under the FAQ’s. Can I suggest that something like that be added to make it easy to figure out how to work the course? Seems like an easy fix.
