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.
Get started now by creating a new collection.

Ranks of katas are not perfect science, they are shared across languages and the difficulty can vary a lot from one to another. Moreover the criterias evolved with times, old katas tend to be easier. Currently it is not possible to change it, so it's better not to pay too much attention to it.
Did you have problems with sorting by values and then by place in original string?
