I am a very shy people before. However, after being the president of Computer Science Club, I find interest in helping others. For example, as our school’s computer science course is pretty difficult for those students who don’t have fundamental knowledge in this area, I will teach classes to both club members and non-members who have problems in Computer Science. I will review the knowledges in the classes for them and giving them exercises to practice. In the process of helping others, I find myself enjoying the sense of achievement. In common core course, I wish that I can also find this kind of fulfillment by helping other students with their study.
