Atmosphere at Caltech

Hi! Im trying to gather some information about Caltech for my son. Besides the stellar academics at Caltech as well as the high standardized scores and the recs required to get in, I want to ask about the experience of attending Caltech. Current or alumni, what is the atmosphere at Caltech like? How are the students towards each other?

Based on my son’s experience, I can say that the House system helped him develop friendships with several of his classmates, his seniors as well as his juniors. He has visited his friends and some of his friends visited us. The students work on their homework sets together, and this provides another great opportunity to develop friendships. He has been going out to movies, weekend dinners etc. with groups of 6 to 12 friends and more. They play sports etc.The students take care of one another if one of them falls sick etc. All in all, the students are pretty friendly towards one another and take care of one another if they fall sick or if there is a situation requiring help (like forwarding resume at places where the student is interning at)
