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.
Mine failed twice, then succeeded on the third try. The error said I had 14 decimal placed in my column, when the output was clearly showing 2.
Checked it few times, had same effect. Seems that decimals test works properly only after few tries (maybe it was second try)
