This is the time to explore schools that match your needs and also to adjust your needs as you gather more information.
How are the majority of classes taught? Are they lectures or class discussions? Is there a core curriculum that all students are required to take?
What are the students like? Do they seem like people you would be friends with? What do the students do for fun? Are they more artsy or athletic?
Are there fraternities and sororities? How much do they dominate the social scene? What percentage of kids stays on campus over the weekend? What percentages of kids participate in sports?
How does the campus make you feel? Can you see yourself here for the next four years? What are the dorms like? How easy is it to get to town or a nearby city?
