That shows that you haven't integrated into college life. You should be more active and cheerful, join more clubs or run for class committees, and exercise your ability to deal with people and communicate with others. After strengthening my ability, I will have more friends around me and have a good relationship with my classmates, so that no matter who I sit next to, I can answer questions easily and fluently without feeling embarrassed. Therefore, the most important thing is to be open-minded and not too introverted like high school.
