Classmate, the question you asked is not very clear. First of all, what Japanese are you not studying hard to prepare for the college entrance examination? I don't quite understand this point, because most of us started to learn Japanese from scratch after the college entrance examination. Secondly, if you study now, you won't pass the exam, because if you want to enter a better university, you won't have so much experience to learn Japanese, so I advise you that if you really want to learn, you can recite it when you get good grades in the college entrance examination or when you go online to find Japanese pentasyllables now. It's not too late to go to college to learn Japanese. For example, some students in our school study ahead of time, and some have taken exams for several years. But once in the same learning environment, first of all, everyone's teaching quality is synchronous, and learning is the same. What are you studying in college now? I don't know what your hurry is. Besides, learning a language requires several people to practice dialogue. Because it's a major, you can't be careless. So you can take the college entrance examination to heart now and then think about other things. If you have any questions, you can continue to ask, and I will help you answer them.
