My Brown grad is a fond alum. I was racking my brain to try to think of anything she has ever said that is a negative. I finally remembered. She wasn’t that thrilled about her first advisor or Meiklejohn (peer advisor). But she decided to take a Chemistry advisor when she was really doing Physics mostly so perhaps it was her own fault. So I guess advising can be a mixed bag. Or you need to be proactive and switch if the fit is not there. Anyway when she switched to math/cs major she loved her faculty and advisors and felt she had multiple mentors to turn to. She also became a Meiklejohn herself. It is easy to be a little lost and bewildered as a freshman because of the dizzying array of choices and the desire to take more than there is room for.
I do not know any inside scoop on the others.
