Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

I encountered the same issue. I think the test code is faulty.
Please I think you should review the last few incProgress tests. It should be from (8, 7, 91) to (8, 8, 1) then finally (8, 8, 4). It's preventing my code from passing the tests.
I love this!
