In Germany there is intensive language course called Integrationskurs. It teaches German language from 0 to B1 level which is basic level of language understanding which allows to understand and talk about simple topics, but quite freely. I don't know if it's what you meant, but level higher is needed to start study in Germany - B2. Course consist of 600 lessons units (450h) and takes 6 months with lessons Monday - Friday 4 or 5h per day. I think around 30% of people manages to pass after 600 lessons. It's partially because many students don't have big motivation or don't know how to study effectively or their native language is very distant from German or it's their first foreign language and they're older.
So if that website is correct and Polish takes 47% more time to learn, then you have a chance to learn it up to basic B1 level in 9 months (around 900 lessons)
B1:
