Learning Danish is easy....
... ;-) hummm at least it is most of the times pretty cheap!
The Nordsjælland school where I have done my study is apparently in the "rich" category. Education 100% free (well I wasn't asked to pay anything yet), e-learning classes, small groups courses on evenings or on Saturdays, teacher available by mail to correct your exercises in between classes, language lab in a computer room, books provided, CD-ROMs, dictionaries ... is luxury!
