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.
How do I get it to throw an Argument Exception? Seems like everything works with my code but I'm not getting the proper error codes that the kata wants. I'm using try, catch, and throw but I can't seem to get the ArgumentException that it stupidly needs. Pretty annoying actually, this is not a helpful problem.
