After you have added a few kata to a collection you and others can train on the kata contained within the collection.

why is my total column getting the bigdecimal instead of common integer value?
when does the bigdecimal happen and how to convert them to integer?
It took about 100ms with the "run examples" but it got the error on "attempt" saying that it takes longer than 120000ms. Any tips?
