Graded_Exercises_Score_Conversions

Graded Exercises are a chance to practice the skills and concepts we learn in class.
Since they are exercises, they are not, by themselves, good indicators of excellence. However, consistent mastery of the Graded Exercises is one important component of the pursuit of excellence. Therefore, the cumulative scores on Graded Exercises will be converted into a Quality Point grade for the chapter, according to this scale.
