Hi guys, actually I am at the first year of the Master degree in Computer Science in Italy. After the university, I would like to work outside my country. Therefore I think I will need a good English to be desirable in the jobs market. At present, I study english books, the course holds in english, therefore I have an acceptable level of reading and listening but, as you probably noticed, I haven't got a good speaking and writing. So, the big question in my mind is this: should I go on Erasmus for 6/9 months in UK or northern Europe country? Or should I stay in Italy, graduate, take a good certification and then look for a job from Italy? My fears are two: I will go in a foreign country but I won't learn a proper english and I'll learn bad habits that will be hard to unlearn next. Or I'll stay in Italy, I'll learn a "academic" english (and I'll gain a certification) but I will not have opportunities to find a job from Italy because I will not have connections in a foreign country.
