Current IU student here. Housing is all off campus. Many students live in apartments/rent houses very close to the optometry building and there are many buses that stop at the building. I live further off campus so I drive, park my car, and then walk to school. You are correct that you won't be seeing patients until your second year but I actually enjoy that. There are so many things to learn and skills to master before seeing actual patients (and the tiny amount of free time I have in my day I want to spend on something completely unrelated to optometry
). Admissions day is very chill so just relax, and be yourself. Good luck!
