For each course, your faculty member will provide a syllabus describing in detail how he/she assigns points for assignments, Learning Team activities, and class participation. There is also a clear breakdown of the point distribution for grading.
University of Phoenix provides a recommended structure for grade distribution, which you can view in the catalog. However, it is up to each faculty member to determine how he/she will distribute point values.
Be sure to read and understand the instructor's syllabus at the beginning of each course.
