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.

Among my testcases there was a call against string with single quote, like "foos aren't bars", while expected result was "Foos Aren't Bars". But "aren't".title() equals "Aren'T", so solution using it doesn't work, and yet it's at the top. So, different people given different testcases, some get "harder" cases, which causes them to write more complex code than other people.
