Hello Gray, It depends on what level you are at JLPT N5 - I would need to assess your level of Japanese but I would say it would not be impossible to pass JLPT N4, again, depending on your current level. The best study materials are: Shin-Kanzen Master JLPT N4 Grammar, Try! N4 and actual mock exams on JLPT N4. May I ask how you have assessed you are at N5 level? Yours, Issei

I want to live in South Korea because I like everything about it. I also like Korean people. They always work hard and are independent.

Please correct the next sentence. Until which section have you finished? どの課まで（何課まで）終わりましたか。 I don't think you can use "until" in that way - since "until" describes the end of an ongoing motion, it specifically is talking about a specific time = when. So, to say "until which section have you finished?" is the same as saying "When which section have you finished?" respectively. Just as you cannot use "have + p.p." if you are referring to a specific point in time, until is the opposite and "until" and the present perfect cannot be used together. I think it should be "By/Up to which section did you finish?" - in this case, the the completion of activity is clearly marked by "by which" and because it is talking about a specific time/event, simple past is the only candidate.
