Testing feature on ListeningPractice

Hello,

A month ago I started a website where you can practice your listening skills for free in 12 languages (see the topic here: New Free Listening Practice Site With 11 Languages - Lang...). Yesterday I added a new feature called ‘testing’ where your answer are rated automatically and you don’t have to type at all. I would like to know your opinions about it and how you think this feature could be improved. You can find it on http://www.listeningpractice.org.
