Normally when I send an e-mail like this to students I say something like:
Dear blah blah,
My name is blah blah from blah blah. In order to assure you are put in the right level of language course, please inform me what previous experience you've had with the language and send documentation, etc.
Well, I don't think this girl even knows I work here but it would be strange to be like, "Hey, it's me. I work for the place where you're coming to study in the fall. I know you've taken this language before but I need proof of what level you're in."
How should I phrase this e-mail so it doesn't sound weird/stalkerish?
