Swedish educational system sucks, which is proved by how low the Swedish standards are, compared to the rest of the Europe. In Croatia the students need to know multiplication and divation before the end of first grade, but in Sweden the norm is to start such education by the fourth grade. Swedish schools are incredibly easy, I fail to see how any person without a handicap can fail any class no matter what course or age. Unless you don' t attend... Which often doesn' t matter either. I had 56% absence from my English lessons, never did anything, not even homework. Then I did the last final exam and got an MVG+ which is similar to more internationally known A+. So then I got an A- for the entire course!
The reason why we swedes know English so well I believe is because we do NOT dub the the movies or television shows... At least that' s my reason, I learned it all from cable tv Cartoon Network.
I currently speak Swedish, English, Croatian, a bit Russian, Japanese (mind you I do NOT read ANY), my Spanish is rusting but I do O.K, but my Deutsch has faded completely over the last couple of years, when I haven' t used it, now I can understand some when people speak, but It' s near impossible for me to build own sentences.
I' d also like to point out that the more languages one learn, the harder it is to think out a sentence quickly and many will problably recognise the feeling when yo are supposed to say a certain word in you own mother tongue, but you can only think of the same word but in another language. Also, my own thoughts are nowadays a mixture of Swedish, English, Croatian, and Japanese... It' s fucking annoying!
