Hehe ~ I'm also a junior girl. This kind of thing has happened to me. First of all, you have to admit your mistake and have a correct attitude. Whether he is wrong or you are wrong. After all, he is a teacher. If you want him to give in, you have to give him a step down.

Then it is to further win over the relationship. Gifts are of course the most effective. You can make an appointment with him to deliver it to his home. Say something he likes to hear. He is full of flattery and doesn't think so. Of course, even if it is flattering, it should be taken naturally, just like from the heart. Finally, in the future college life, I will tell you the truth. You must have a good relationship with the counselor. The attitude towards the guide is: always respect and obey. If you don't accept it, you have to show that you are right.

I say this because most university tutors are difficult to deal with. This is the least harmful way for both sides.
