What do you wish you had asked during you Case visit?
Planning to visit soon.
I think at any college:
What is freshman orientation like?
What are the labs in your major like (see if you can visit)
What are the dorms like?
Where can you eat besides the cafeteria?
How can you use transportation to get home?
Do they have a writing center for extra help?
How do you connect with a professor to do research?
Ask about your extra curriculars you are interested in
Encourage you to visit during admitted student days or a big open house event. They are well planned with lots of activities and lots of access to various departments and labs.
