Chinese Radio Section 4: 4/4 words you should know are not yet introduced.
Well, it makes sense that I cannot comprehend anything in the Chinese Section 4 radio, if they are filled with unknown words.Everyone of those 4 words have not yet been introduced. And I know that they are unknown words because I add every new word Duolingo introduces to my flashcard app (Hanly). I also spend a lot of time on comprehensible input on YouTube, graded readers with audio where I see fine progress.
But the radio units in section 4 are straight up impossible at the level you are supposed to have at that level.
Very demotivating to progress in Duolingo when these incomprehensible lessons show op.
