It helps when they have a major in mind. It’s hard to set up meetings with professors and advisors when they have no idea what they want to go into. Once S20 figured out he wants to major in environmental science, he was able to set up meetings with people in the department.
I really enjoy it as well. The visits have been a great excuse for us to take some family trips and I’ve done a few with just me and S or D and those have been great one-on-one time.
