How does the Webflow certification course work?

I’m interested in becoming a “professional partner.” To do that, it says here that I need to take and pass the requisite certification course.

However it is not clear how I’m supposed to go about that. I’m assuming this is the course I’m supposed to do, although there’s no clear indication of that: https://university.webflow.com/courses

But I don’t understand how this works. Do I need to do all of those in the library? Who will review my work? Do I just need to do that or will I be tested afterwards? If not then how exactly do I acquire the certification?
