Translation of optimize in Spanish

I'm Ricky. I am learning English at school here in Switzerland and at the same time I am learning Italian. You writing skills are very good. Where did you go on your last vacation? See you next week.
Yes, my Spanish is much better than your German, but it is not true that I do not want to learn with you. I think this is not an issue. Where do you come from in the U.S.? East or West coast?
Tomorrow I have my test, so I have to practice a lot, but it should have started to study much earlier. I can only act under time pressure, I'm just like that... . I am 25 years old and I am married.
