Well, my mother tongue is Spanish, obviously... I learned English in a bilingual school when I was very little, and I had to deal with it a lot of times (specially in school... my marks in English were the highest of my classroom, and English saved my life in my previous exam to access University...)However I lost a little the use of it, and there is always a mistake on my texts, so I can't say that it's really perfect.
I studied French on school, but I forgot about it almost completely... my level is below the basics, actually... and I'm studying Japanese right now. And I think that's all... ^^U
