Well, the grammar lessons of my course were really good, and one of my teachers said that I was the best student that he had had in 10 years, and the course wasn't completely bad. But look at me, look at how me, one of the best students only ended up understanding 30% of the things they say in films because of their reluctance to teaching with ipa!
I know like maybe 12000 words in English and I now have to relearn everything from scratch! I learned my 12000 words by studying like 30 words per day for like 2 years, hard work! really hard! I could be learning another language now instead of losing the time relearning the correct English pronunciation now! :D but I'll have to do it or the course will be useless with my 30%
