WordBanker tests you in sessions of 20 words a session. Once you have been tested on those 20 words you will automatically be taken to round 2 where you are tested only on the words you got wrong. Once all words have been translated correctly the session ends.
Translate a word correctly three times in the first round and you will be given the option to bank that word. Once a word has been banked you will not be tested on it again. This way you only get tested on the words you don't know.
Everyone has their own way of learning so WordBanker is easily customised so you can change testing and practice methods to suit yourself.
