In terms of your clinicals at Ross, you can do both, either do all your rotations in one hospital OR go to a different hospital for each rotation.
As you might already know, you have core rotations and electives: some students choose to do all their cores at one hospital, others choose to move around.
There are of course advantages and disadvantages of each. The states/hospitals where you can do all your core rotations include: Chicago (Jackson Park/St.Anthony)
New York (Wyckoff Heights or other nearby hospitals)
California (Kern County)
-the advantages: stay in one place, dont' have to worry about moving every few months
-the disadvantages: may not have the best rotations (some cores better than others)
You can of course choose to do the core rotations at different hosptals (or different states!). I myself have chosen to do this.
-the advantages: guaranteed best core rotation (teaching experience), see different parts of the US, meet different types of people.
-the disadvantages: keep moving from state to state, must deal with finding places to live, must be mobile (i.e. have a car!).
Just be sure, that as soon as you have your step 1 scores, to request where you would like to do your rotations!
