What Plugins Power Divi University’s Courses and Community?

Hi Mak! I’m really impressed with how you’ve built Divi University.
I’m currently working with a primary school that wants to create an educational platform where:
– Teachers can create courses and activities
– Students can access courses based on the group/class they belong to
– Teachers can grade students
I’d love to know which plugins you’re using to manage:
– The courses and lessons (LMS / course plugin)
– The community/groups and member area
We are planning to build something similar with Divi 5, ideally using plugins that are fully compatible with Divi.
Also, do you have (or plan to create) any course or training specifically about building an educational platform with Divi 5?
Thanks in advance for any guidance you can share!
