Courses on this page comprise more than 20,000 pages of classes being taught worldwide. Dr. Rick Griffith wrote 28 of the 48 PDF courses (and 28 of the 31 Word courses), but others have contributed their areas of expertise. The number appended to each file name shows the number of pages in it. Many have associated PPT slides in their respective course. You may freely download and use courses in PDF (better for showing images) or Microsoft Word (easier to edit or translate).
