I know the Joyo Kanji, and am studying Jinmeiyou Kanji, and I can read Japanese wikipedia articles and raw manga, though sometimes I have to think for a while to understand what a sentence means or look up a word from the dictionary. I can watch some anime shows without subtitles but that depends on how difficult the language used is, and my hearing comprehension isn't perfect either, so I still need to study more, but I'm hoping that in the next 4-5 months
Damn, how far into high school are you? Also did you take Japanese on your own or part of school?
