Translation of mention in Spanish

I am studying economics for my MA at University of California and I should stay in the US for about 4 years. My English is not good. But I want learn this language. You want learn German? yes I can teach you German. I wish you a nice day.
I hope, you'll not be disagreeing with me, if i tell you the fact that Italian is very similar to Spanish. i keep my fingers crossed for you! Good luck in your exam and I hope to communicate with you after that.
If you want we can exchange messages and emails in English and Spanish in order to improve and get some exercise. I think we should correct each other's messages. i need to practice otherwise I will forget everything.
