Do you know JLPT?
Do you know that there is a Japanese Language Proficiency Test?
I put the URL because the practice questions were on.
Please try a challenge!
Thanks for the link. Even if it's a little bit higher than my level I tried the N2 one, when I was thinking the listening section was kind of easier than I expected, I failed two questions in a row :(
Here's my result, I know nobody cares but https://i.imgur.com/kVwZjqy.jpg
The reading comprehension section was pretty hard, I was getting a headache, but I was surprised that they put furigana in a common expression like 一生懸命 and yet there were some words I couldn't read and no furigana, probably it depends on the kind of materials you read. I should read much muuch more, but the fact that I didn't do so bad at that level gave me a bit of confidence.
More than learning vocabulary in isolation the best thing is probably reading a lot
