Actually, it depends on how hard you're going to study... Anyway, even if you study really hard, like 2-3 hours every day, it will take not less than 1 year just to get ready to start speaking. Fluency will come later - maybe after 2 more years! )) Learning a language is really an "organic" process. You can slow it down or even stop, but you can't make it go faster! It takes 90 days to grow potatoes, no matter how many times you water and cultivate it... So, if you wanna have success, take your time and be patient!
