French language problem?

So, these days I'm thinking about going to university in Paris...Next year I'm finishing my high school and since I have an aunt in Paris, I thought about going there...The problem is language...I've been learning French for 3 years(one more year to go) and I don't think that I'm really qualified to study on that language...So,I was wondering if someone could help me to upgrade my knowledge, or give me only some advice...Thanks in advance
