Answer:

It’s easy, albeit a little slow in a browser from our experience, but slow Fusion is better than no Fusion! Your kids must have a student community log in in order for this to work. I did this last year with all of my students, and it makes this process very easy… Otherwise there is one extra step:

1. Go to Autodesk student community and sign up: https://www.autodesk.com/education/home
2. Go to Autodesks, “MyHub” and log in: http://myhub.autodesk360.com 
3. Click on “New”
   
4. Start  a new design OR start a new folder.

We strongly suggest they make a new folder for each assignment you give them.
