need to practice english, to be fluent

Hi everyone!

I'm a 22 years old french student living in Paris. I need your help. In fact, next week, I'm gonna have an interview of 30 minutes for an internship en England all done in english and I need to get prepared. I would like so much before this improve my level of english because I don't feel very confortable with it. I hope someone ( a native english person) can help me out!! In exchange, of course, I can teach french or spanish or portuguese!!

Hope you'll hear me!

Bye bye

Merci

Yves
