How long does it take from Japanese 0 to n5? Which tutor is good in Shijiazhuang Summer Japanese Specialized School?

I officially got the standard Japanese textbook Elementary Up and Down in February 20 17 (later I switched to New Japanese), which means that it only took me one year to reach the level of n2. So how long did it take to reach the lowest level n5 in Japan? About a month. This length of time is based on not less than three hours of Japanese study every day. I remember it was from seven o'clock to nearly ten o'clock after dinner in the evening. The specific operation is to learn a new lesson, read grammar and words quickly, get a slight impression, and then find a face-to-face lecture. You must find a school with a high pass rate in Japanese exams in previous years. Mr. Wang, who came back from Japan, is highly recommended here. He speaks grammar carefully and can speak it easily. Of course, other teachers can also teach. The point is that his family is not an OEM. Then read a book by yourself, read the grammar carefully again, and then you can read through the dialogue in each lesson and start memorizing words at the same time. N5 words are not difficult and easy to recite. In this way, I can always finish two classes every night, and after learning a textbook in about 20 days, I will have the level of n5 (of course, words are still very important, which is an important criterion for whether n5 meets the standard).
