1, first of all, his grades in college must be excellent, because he is completely self-taught in college. If his grades are excellent enough, it shows that he has a good habit of self-study, so that his summary of knowledge points is better than that of ordinary people, as good as that of full-time teachers. If he is good enough, he is even better than a full-time teacher. At the same time, one of his own study habits is also a place to learn.
2. College students are almost the same age as senior three students, and they are all young people. It is easy for them to have the same topic and become friends. In high school, especially when senior three students are nervous, having a friend to talk to can relieve the pressure well. At the same time, young people are most likely to imitate the behavior of their peers, so that you can be influenced by the good habits of college students in the learning process, not just for your high school study.
3, why don't I recommend full-time teachers, because now everyone knows that full-time teachers in senior three are very busy, and secondly there are families to care about. Even if we say that full-time teachers are experienced, it is impossible to have a lot of time allocated to you, that is, to give you lessons. As for the recommended full-time teachers upstairs, it makes sense, but for an excellent college student who has participated in the college entrance examination, his experience is more suitable for students. Moreover, he has more time to communicate with students, not only in study, life and psychology, which is unmatched by full-time teachers. In addition, full-time teachers are all teaching in large classes, and his teaching method is facing dozens of students. This teaching method may not be suitable for you (it's not that full-time teachers don't want to arrange different teaching methods for different students, but that they are too busy and don't have enough energy and time).
I don't know if my reasons are sufficient. If you want to seek counseling from college students, according to what I said above, you must have excellent grades and a cheerful personality. Of course, you must see for yourself whether it suits you. If you want to find a full-time teacher, try to find a younger teacher, because young teachers are very attentive to their students. Unless you can find a good old teacher and talk with the students, you will just move the school to your home and be very tired.
