Residency year....

Hi everybody !

Just wondering what a residency year is like for internal medicine in a university hospital in most states ??

Do you have 4/5 rotations, with with sub areas??
Do you have a compulsory ER rotation plus surgery?
( this is the case in most Australian hospitals, irrespective of whatever field anyone is interested in we just get a package and have got to deal with that for the whole year )

I really appreciate your response/s..
