Student experiences

"A life-changing experience. Cornell fostered my curiosity and helped me grow so much. The class was immersive, fun, and eye opening. My professors were wonderful. I gained an advantage in the college admissions process, as I now know what I’m looking for in a school. I’m addition, I feel less anxious about college life."
"Fantastic... Your professors, your classmates, your dorm neighbors are all there to help you really learn about your class, to help you learn from one another, but most of all, to help you learn about yourself. It’s a phenomenal experience, and definitely one I will remember always. If you are given the chance, do it."
