1, if the learning ability is average, it will take about 1 year to pass the second level of Japanese. This is self-study, and you must have a strict implementation study plan. If you are very capable, it will take about 6 months for some self-study partners.
2. If you sign up for a class, there are entity learning and online learning now. Generally speaking, it depends on your study plan. If you have less time, it is recommended to consider taking training courses online, so that you have more time. For example, I know a teacher who often gives lectures for free. Write down the last three numbers 280 plus the last three numbers 894, and then his Q appears. If you have any questions, you can always ask him.
3. The length of time has a great relationship with the selected textbooks and books. If it's just for the entrance exam, I suggest buying a new version of standard Japanese and downloading a set of teaching videos, so that learning together will be much faster. Of course, the teacher I introduced also has free videos, so you can ask him for them.
4. Prepare a set of teaching materials by yourself. If you study Japanese because you like anime, I suggest choosing the new editions of Standard Japanese and Everybody's Japanese. These two books are still very good. If you are going to study abroad, it is best to use comprehensive Japanese and new Japanese for the postgraduate entrance examination.
Note: Be sure to make a daily, monthly and quarterly study plan for yourself, which can save you a lot of time, such as my daily study time now.
Morning: Get up for 30 minutes to practice oral English, record it on your mobile phone and listen to it every day. Recite words for 30 minutes, not asking for many words, but doing your best.
Afternoon: After lunch break, review the lessons to be learned in the evening, so as to be aware of them.
Evening: I will spend two hours watching videos to learn a lesson, and then do supporting exercises.
Monthly plan: do two sets of simulated test questions and talk to two Japanese people, and no one will talk for 30 minutes.
Quarterly plan: for this quarter's study, do a systematic consolidation and study, make a review plan, and make an evaluation of yourself.
