We have become aware of some problems with Student Data files that affect student answers to exercises and assessments. The files occur on Version 1.0 of the Student Resources disc (as well as on the Instructor Resources disc). A new set of files (Version 1.1) have been posted in the “Computer Lab,” located on the Student side of this IRC. Students should be sure to use these files as they complete their exercises. We apologize for any inconvenience.
