Translation of observe in Spanish

I was wondering if you can tell me if few words how to study here because I don't know that's why I'm not on line most of the time,thanks. Can you help me explaining me how to do the lessons, I still don't understand it
I can understand a little Spanish with the base of Italian and heaps of words sound familiar. I will try to have conversations as much as i can. Just learning the vocabulary and the grammar isn't enough!
Many thanks for your letter. I am delighted to tell you that I have passed my exams and am looking forward to the next year. Meanwhile I am planning a trip to Costa Rica and some places around there.
