The BSI Classroom is located in the Gold Biosciences building on the University of Colorado Boulder Main Campus.
From Colorado Avenue, looking north at Gold Biosciences, enter through the eastmost door of the building along Colorado Ave. You should see two red signs, "Gold Biosciences" and "Door 8" on either side of the entrance door. If you pass a statue of a buffalo or Folsom Field, you have gone too far east. If Colorado Ave. starts to curve south, you've gone too far west. Once inside Gold Biosciences, head straight down the hallway. Walk almost to the end of that hallway and turn left down a short corridor. The BSI Classroom, Gold A1B20, is at the end of that corridor on your left.
