I need an answer from a swede. Do you pronounce "sj" as the "ch" in German "ach"? If so I would be happy because I have a hard time pronouncing "sj".
Once someone told me that the "sj"-sound sounds like the "who" sound in English and a YouTuber told in a video that "sj" is pronounced as in Spanish "juan" the "ju" part but she told that it comes from the lungs
Idk if its like German I would be happy
No, sorry. It's not close to the ch in ach at all. The Juan comparison is much better.
Former course contributor Blehg has a series of videos explaining the sound. The first one deals with pronunciation, but you may find all three interesting.
