If your student earns a low score on the Facts Quiz, they should retake it until a good score is achieved. Unlike the Review Questions and Exams, only the highest score on the Facts Quiz is recorded in the online grade book.
Keep in mind, the Facts Quizzes are LEARNING activities that help the student learn the material. We are not testing their knowledge at this point. Because they are learning activities, the grades are a small percentage of the overall grade.
To learn more about grades and how to complete these activities, see Grading in the Teacher's Guide for your course.
