The foundation course assures that you have a solid basis for taking technical courses in the minor. These courses are not simply about how to turn on a computer--they give you a grounding in understanding and using computer systems, as well as word processing, spreadsheet, and database software. This grounding is required for other courses in the minor--the instructors in those courses will assume you know the basics.
If you believe that you can document equivalent learning, discuss this with the IT advisor. Any exemptions to Curriculum or Foundation waiver must be approved by the IT Program Director.
