Math 147B Announcements

12/16/2022 a. Your section BS now shows the accurate final exam grade for each student. One of the problems had been graded inaccurately for some of you if you had the (yellow) version B of the exam, and it took until late afternoon today (Sat) to get everything straightened out. Most but not all of you have had their score improved as a result.
b. Your letter grade is computed according to the Spreadsheet math147B-grades-examples.xlsx. That link can also be found on the course materials page. You can figure out what that grade will be according to the following explanations:
QSum = sum of all 12 quizzes
QuizAdj = sum of best 10 quizzes
  • Examples:
    • User Charlie loses zero because two lowest quizzes = 0 + 0 = 0
    • User Delta loses 10 because two lowest quizzes = 5 + 5 = 10
    • User India loses 20 because two lowest quizzes = 10 + 10 = 20
HwSum = sum of all 5 graded HW
QuizAdj = sum of best 4 graded HW
  • Examples:
    • User Charlie loses 20 because lowest HW = 20
    • User Frances loses zero because lowest HW = 0
    • User Hotel loses 5 because lowest HW = 5
TotSum = sum of attendance + all major exams + all 12 quizzes + all 5 graded HW
TotAdj = sum of attendance + all major exams + best 10 quizzes + best 4 graded HW
  • Examples:
    • User Golf: Both figures are the same because zero points were lost on both quizzes and HW
    • User Frances: 10 points were subtracted because 5 + 5 points were lost on the lowest two quizzes.
Add-20: Boosts your score by 20 points. Explained further in item c below.
Grade: The letter grade you would have gotten if I had applied the grading scale displayed in the "Your Grade" section near the end of the syllabus to the points total in the TotAdj column of the spreadsheet. Instead:Grade+20: This will be your letter grade! It results from applying the grading scale displayed in the "Your Grade" section near the end of the syllabus to the points total in the TotAdj column of the spreadsheet.   • Examples: If your Grade+20 score is 780 then you will receive a B. If it is 848 then you will receive a B+.
Thus, You can compute your letter grade as follows: Take one of the users, say, Alpha, and overwrite the columns G (attendance) through AB (Hw E) with your BS data. The spreadsheet will compute the other columns, including Grade+20, for you.
c. Instead of a curve: I have given everyone of you 20 additional points. Fifteen of those are meant to boost your grade, the other five are there to ensure that nobody missed the next better grade by five or less points.
Accordingly, I am not open to discussions about improving your grade because you only need two or three extra points.
d. You can find the anonymous grades for the final on the grades page.
e. It was my privilege to be your instructor. I hope that the grade you obtained is what you were looking for, and I wish you all a wonderful semester break, and all the best for your future -- Michael Fochler --
12/16/2022 I won't be able to start determining your letter grade until all finals are completely graded.
At that time I will review the grades and decide on whether there will be a curve and if so, how many points I will add.
I expect this will be done Sat afternoon. If I cannot make that deadline then I will send another announcement.
