Histograms of the class's Exam scores will be posted on this page (look toward the bottom of this page).

Ignore any information Scholar might give you about your Course Grade --- its computation of your final grade for the class is bogus.

Results for Exam 1

Each question on the exam was worth 1 point, so the highest possible score would be 15.
Class average = 11.0
Standard deviation = 2.2
Median = 11
Highest score in the class = 14

Results for Exam 2

Each question on the exam was worth 1 point, so the highest possible score would be 15.
Class average = 10.5
Standard deviation = 2.8
Median = 10
Highest score in the class = 15

Results for the Course, So Far (Current results after 6 HWs, 2 Exams, and 1 IRA)

Your Exams, combined, are worth 60% of your final grade. Your HW, combined, are worth 20% of your final grade. And your IRAs, combined, are worth 20% of your final grade.

So, the equation to determine your final score in the course is
Score = ( (0.6 * Exam_average)/15 + (0.2 * HW_average)/10 + (0.2 * IRA_average)/10 ) * 15.

You can use that equation to compute your current score.

The max you can score is 15 points for the course.
Current class final score average = 11.7
Standard deviation = 1.9
Median = 11.7
Highest score in the class = 14.7

The histogram below shows the distribution of current course scores.

"Approximate Letter Grade Divisions" are given below. They are indicative of the letter grades I would assign to everyone if the class ended today.



Approximate Letter Grade Divisions:
12.5 - 15.0: A
10.0 - 12.5: B
7.5 - 10.0: C
5.0 - 7.5: D
< 5.0: F
