Final grading summary
Calculus A: Spring 2022
I did not compute summary statistics on final exam scores
or any other items (such as overall grade), because of
the small size of our class. This document
will show you how to compute your own overall grade,
as well as what letter grade it corresponds to.
How to compute
your overall grade
Note that the "Course total" percentage shown in
Moodle is your correct overall /final grade.
I will recap the grading breakdown here, and describe
how to calculate your own grade using the numbers shown
in Moodle.
Overall grade includes all the assessed items in the course.
We had 13 homeworks, 10 quizzes (including the makeup),
9 classwork/labs, 3 tests, and the final exam.
One lowest grades was dropped from the homework,
and one from the quizzes. If you took the makeup quiz,
then we effectively dropped two lowest quiz scores for you.
Here is a recap of the grading distribution as stated in
the syllabus:
Homework = 10%
Quizzes = 15%
Classwork/ Labs = 15%
Tests = 15% x 3 tests = 45%
Final exam = 15%
Here is how you
would calculate overall grade using your own data:
Step1: Recall, your final exam score replaces your
lowest exam score if that improves your overall grade. In other
words, this applies if your lowest performance is not on the final.
To implement this, I recorded your
your final exam grade twice in the Moodle gradebook.
Here is how: a duplicate copy of your
final exam grade was added to your test scores in the
form of a 4th test.
I also counted your final exam grade separately,
on its own. See Step 2 below for details.
Step2:
(Add top 12 homeworks)\(\times \frac{10}{300}\) +
(Add top 8 quizzes) \(\times \frac{15}{48} \) +
(Add all 9 labs)\(\times \frac{15}{90}\) +
(Add top 3 tests, counting the final as the 4th test)
\(\times \frac{45}{150}\) +
(Final exam)\(\times \frac{15}{50}\)
This number is your overall grade (on 100%).
[If you want to understand this formula, for each category
the numerator is the percentage weight, and denominator is
total possible points on that category. Recall: there were
12 homeworks
worth 25 points each (12\(\times\)25=300), 9 classwork/labs
worth 10 points (9\(\times\)10=90), 8 quizzes worth 6 points
each (8\(\times\)6=48), etc. So, if you made full credit
on every item in the course, your overall grade would be
exactly 100%.]
Letter grade
boundaries
Letter grades were assigned based on the following
boundaries (written in standard open/closed interval notation):
A+ = [89, 100];
A = [84, 89);
A- = [81, 84)
B+ = [78, 81);
B = [73, 78);
B- = [70, 73)
C+ = [67, 70);
C = [62, 67);
C- = [59, 62)
For example, a student whose overall grade is 80.97%
would make a grade of B+. I do not round
up (or down) -- for example, 80.97% doesn't
become 81%, it stays 80.97%.
