It's the end of the semester and you have completed all but 3 Keeping Score exercises for a total of 180 points. You have not taken advantage of the extra credit opportunities (assume that there were 200 points of extra credit available). Your performance on the three midterm exams has earned you a total of 1,200 points (you basically earned a low B on each midterm). You completed the SONA requirement, earning the full 200 points. You did not complete the syllabus exam for zero points. Nor did you complete the on-line practice exams from the text, opting instead to buy a used book for which no web-site access was available. Thus, you currently have a total of 1,580 points of the available 2,490 points. What will be your percentage grade in the class? Round your answer to the nearest one percent. Do not include the % sign in your answer. For example, if your answer is 50.3% then you would enter 50.
