RELATIONSHIP AMONG COURSES CS 625 shares lecture sessions with CS 425 and CS 725. CS 625 is the "pivot" course between CS 425 and CS 725: CS 425 simplifies CS 625. A popular scheme is for the 425 student to do all the work assigned to the CS 625 student but with an "allowance" whereby grading can be skewed by choosing "best" portions. See below for more information on CS 425. CS 782 students normally take a lead in project work creating more scientific documents, fully referenced, etc.
