Translation of oscillation in Spanish

You can always write me and we can learn together any language you want. How long you have taken classes? Was it only at night or on weekends? Makes me wonder how someone can be so fluent in Spanish.
Are you currently buried in a lot of work? I am not, because the financial crisis has put me back on hold. I do not work, so I have time for going out in the evening and being online.
That is a beautiful name you have got. It would be very helpful if you answered my mail before next week because I will have my final test on Wednesday. I will understand if you won't be able too.
