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.
Get started now by creating a new collection.
"NOTE: There will also be lists tested of lengths upwards of 10,000,000 elements. Be sure your code doesn't time out."
You only get to the next rank if the progress for you current rank reaches 100.
Therefore, solving a rank -8 kata on a rank -7 account will give you 1 point, not 1 rank, thus your rank will remain -8 and you will have progress = 1.
