Learning Swedish in 3 months

Hi, I'm going to Sweden for 3 months on a student exchange.  I'm a native English speaker.  How possible would it be to learn Swedish during this time abroad immersed in the language?

I'd seriously advice Paul Pimsleur, it's amazingly efficient. Great for listening during transport or any daily activities which don't require your concentration

May I ask as to what reason you were in Stockholm? Where are you from and where are you now?
I'd love to live or work in Norway or Sweden.
Tusen tack
