You can tell your monitor and ask for help and give you some advice. Whether you find it difficult to learn English or math, listen to others and then slowly integrate and study with you. Have fun there. You can call the teacher. If you are shy, I heard that you just graduated from college. You shouldn't be too quiet and depressed. You can try to talk to others, but you can't adapt to the new environment, and you will gradually start to have friends to chat with you. If you have any questions, you can tell me. If you don't know how to make friends, I will try my best to help you, otherwise no one will be with you. I hope I can help you to adapt to the new environment quickly. They like students who often ask questions; Don't worry about the new environment The students are very friendly and very good.
