Translation of einarbeiten

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.
Until now I have tried the copy the mode of operation of Mike in class. Even the homework that they gave us do not match the exercise that we tried yesterday. I could not fulfill this task anyway.
I would be pleased if we can still keep the contact alive. In the future I will have more time to write emails in Spanish. At the moment I just can't. Sorry for being so direct but this is the truth.
