Prosze: Kilka zdan z mojego Cover Letter

a oto one:
During my studies I have had such curses as: ... i wymieniam

0 pracy:
I have assisted gust’s from different countries; mostly Germans and Swedes. It has been a good practice for my interpersonal, communication and language skills.

During my 5 month stay in Italy I’ve learnt some Italian culture and language. This program has been for me great and very enriching experience. Now I’m fully aware of the opportunities that UE programs gives to youth and I would like to make a substantial contribution in propagation international mobility.
a może:
prpagation of international mobility
albo
propagation of idea of international mobility

Bardzo prosze o wszelkie sugestie
