sometimes yelp has reviews and pictures of the different prometric centers so that might be worth looking into, but I was also at this place over the summer.
It's an isolated office building and theres plenty of parking surrounding it, like tons of it.
I walked in the building, probably looking noticeably nervous/confused and an employee just said something like, "taking the MCAT?" and told me what floor to take the elevator to, but I'm pretty sure there is a sign that breaks down everything I just didn't have to go looking for it haha.
The bathroom is at the beginning of a hallway that leads to the waiting room/sign in room. The sign in people were nice and quick...I was sitting in my test chair by 7:40AM for an 8AM exam. Don't wear anything with too many pockets, you have to turn them inside out every time you enter/re-enter the room and it can just be annoying and time consuming.
Also, you can call the test center and double check things, they're nice about stuff like that usually so if you wanna know specifics like the exact floor they're located on call 'em.
I can't think of anything else noteworthy, let me know if you think of anything else and best of luck!
