The capital area libraries have a wide range of services they offer on top of lending books; most have boardgames, some lend sports equipment and Kohtaamispaikka in Lasipalatsi quite downtown offers even free digital services. Now they have also started to offer free language courses online for a number of language, including Finnish for foreigners. The courses include training for speaking the language, listening comprehension and grammar, and one can also take tests there to see how well the learning is going.
To do the courses, you only need a library card and a pin code for it. Then you log on at www.helmet.fi/Ekirjasto, then choose either “opiskele kieliä verkossa” or English as a language. The courses should work on a mobile too.
