Test your English vocabulary in use for pre-intermediate and immediate, intermediate and immediate levels as well. We've got jazz, the jazz level, which is when you get to the very top. When you've reached jazz, you can just bibbly, beep, bap, do just let the language roll off your tongue. This is how the English comes out. It just gets transformed into sort of analog funk frequencies that immediately impart all information to the other person you're speaking to in exactly the accent you want. Just too cool.
