The Wikipedia description of A1 is: That seems to perfectly describe him for listening & speaking: he was able to cope with a few basic questions with some patience and assistance from his interlocutor. His grammar was virtually non-existent, more jumbled of words and phrases than sentences. But, his vocabulary was great, and some of his individual phrases were good, common usage, so I'd guess B1 for reading. He suggested in his final video that if were to spend a few evenings immersed in conversation a lot of his passive knowledge would be activated, and I bet he's right. The comment about sounding Japanese was interesting. The other day I had two foreigners with me at work who don't speak Korean, and after an incidental Korean-language exchange between myself and a co-worker, one of them suggested that my words had sounded Japanese to him. In English we all recognize French accents, German accents, and so forth, and I've tried to investigate how Koreans perceive the same in their own language, whether a German-Korean accent is different from an English-Korean accent, and so forth, but I never get a satisfying answer. Perhaps this Japanese-sounding phenomenon may be a manifestation of that. I know my own English accent resembles Mr. Kaufmann's. I'll look into it more.
