I vaguely remember this movie but it is about a girl who is either a geek or very unpopular and she changes her image (possible over the summer, I can not remember) and returns to the school as pretends she is a foreign exchange student from Paris. It is probable a teen movies from the 80s I believe but the details that I remember are sketchy.

Possibly Student Exchange (1987) (TV) (http://www.imdb.com/title/tt0094063/)

Slap Her... She's French (2002) (http://www.imdb.com/title/tt0187512/)

It's Slap her.. She's french.

But in USA title it's... She Get's What She Wants.

The way she described it matches the movie I've listed almost exactly. I'm not stupid, I love that movie.

I'm not stupid either. You gave me a reddie in response to someone else's
Question and didn't allow them to respond for themselves. Mine matched
Their description as well, and if it isn't correct, it's for the person who asked
About the movie to respond. I was about to answer a question you had
Asked which I was SURE about the answer, when I saw what you had done.
