This reminds me of a guy in several of the Japanese classes I took in college. He kept trying to convince the professor that he should be exempt from taking exams because he was president of the anime club and was already basically fluent because he watches so much anime. Everyone including the professor thought he was joking at first lol
The dude could barely make it through one sentence when we would have to read in class
I would get it the other way around, skipping to the test and not taking classes
That’s what I did. Except it was physics, not Japanese.
I loved the Japanese classes I took, but the classroom portions were very low key, and if someone was struggling the professors would basically hold their hand through it. The exams on the other hand were brutal lol
