WordBanker tests you in sessions of 20 words or questions 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.

Answer a word or question 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. 

Warning !!
WordBanker is extremely addictive. You may have to limit your daily intake.
