I had many unforgettable experiences during my college years. First of all, I participated in various club activities in the school, such as the student union and the volunteer association. Through these activities, I made many like-minded friends and exercised my organizational and communication skills.

Secondly, I also participated in some academic competitions, such as mathematical modeling and programming. These competitions have taught me a lot of professional knowledge and improved my problem-solving ability. In these competitions, I worked hard with my teammates and achieved good results, which made me very proud.

Besides, I was lucky enough to take part in the summer internship. During my internship, I deeply understood the operation mode of the enterprise and learned a lot of practical skills. This internship gave me a deeper understanding of my major and laid the foundation for my future career. There are also many wonderful memories of college life. I remember those happy times I spent with my roommate. We study together, play together, care for and support each other. And those days when we traveled with friends, we enjoyed the beautiful scenery and shared each other's joys and sorrows.

In short, college life is rich and colorful, full of challenges and opportunities. During this time, I not only learned professional knowledge, but also made many friends and exercised my ability. These unforgettable experiences will remain in my heart forever.
