Should I get a language course by Rosetta Stone?
If you are willing to put the time in, it is possible to learn a language without having to buy any software. Reviews of Rosetta Stone from what I have seen are mixed, a lot of people have posted questions asking about the effectiveness of Rosetta Stone on Y!A, and responses are very varied. A good webste for learning vocabulary is www.byki.com- this works like flash cards and helps with words and phrases you might find yourself needing. As for which language, if you are in the UK Russian might pay at the moment, as the need for Eastern European language is greatly increasing. Japanese, there are a lot of resources available and the culture is very interesting as well s the language, although this might be more difficult. Don’t have any experience of Persian whatsoever so perhaps can’t advise on that, but if you are likely to use it, go for it! Good luck.
