That is the only way to make the fastest progress. The whole German grammar you can study in 7 days it should not take 6 months as is the case in intensive german classes from A2 to B2. They teach you grammar in small increments with a 30-minute break and the teacher is having a big lunch
in front of her students. Language schools are interested in squeezing money out of your pocket. If I want to clarify a grammatical point that I come across while reading a book, the teacher says it is covered in the b2 level.
They know their drills
I am paying 500 euros per level for an intensive course at a reputed private school in Germany.
I have learned German for 27 months by all myself. Today is my third day attending a formal class. I could understand my teacher with no issues at all. Sure it is a teacher talk but still......it is all spoken in German.
I am there for experience's sake and the more I listen to my classmates speaking German, the more I have realized that Dr. Brown's listening approach method is the right way to go. The sound system of a foreign language grows naturally like a tree. All you have to do is to water the seed every day and have ample patience. In the end, you will see it grow as a tree. if you listen 6 hours every day for 30 months, you will start speaking naturally and correctly.
Before attending this formal class, I have done 3000+ hours of listening in German. I spoke a few sentences in German. I could see an expression of admiration on the teacher's face and on the faces of other girls. I do not know how good my pronunciation is coming along though there are some signs of optimism judging by their facial expressions. I will keep listening every day.
I am there just to get more LISTENING done and to connect certain words with experiences when a teacher is speaking them. I mean, you can get the same experience with an online teacher on italki. Once I increase my YouTubers watching intake I do not think I need to attend such expensive classes.
It is early days but man even intensive classes are way too slow when it comes to exposing yourself to massive exposure. 30-minute lunch break+30 minutes grammar explanation+1 hour grammar drills+30 minutes writing and no feedback at all on writing error5s, well, it is humanely impossible to check the written work of every student.
The only positive so far for me is to listen to a German native speaker speaking as they speak clearly and repeat the same vocabulary a lot to make their language more comprehensible. This is the only reason that I am attending the class.
