Exam format and grading
The exams format is free-style.
The student solves the problems on paper, in her/his own handwriting,
then scans the pages (e.g. with a smartphone) into a single pdf file.
The pdf file is then uploaded to Gradescope.
(This takes a few steps, so please budget enough time for this.)
A submission guide can be found here.
Credit is given only for valid, relevant,
and well-explained solution steps.
Just answers receive little to no credit.
Students may use the textbook, class notes, and a basic calculator.
Using other mathematical software or consulting other people is not permitted.
The hope is that students can be trusted to respect these rules.
Exams are Zoom sessions as well.
All participants must be connected with their video on.
There will be short "interviews" during each exam
with individual students (in Zoom breakout rooms).
Be prepared to provide some basic information
related to your work and testing environment.
The aim is to avoid using remote-proctoring software.
But if it looks necessary after grading an exam,
then the use of Proctorio will be required for subsequent exams.
Each exam is graded on a scale from 0 to 60 points
and is "curved" to a number grade from 0 to 100
via an affine function (example: grade = 10 + 1.5 * points).
The correspondence between number grades and letter grades is
93 -100 A
89 - 92 A-
85 - 88 B+
81 - 84 B
77 - 80 B-
73 - 76 C+
69 - 72 C
65 - 68 C-
61 - 64 D+
57 - 60 D
53 - 56 D-
0 - 52 F
The course grade is obtained via averaging from the
number grades on the three exams, the quiz, and the homework.
Midterm 1: Tue Sep 29, 11:00 am - 12:15 pm (weight 20%)
Midterm 2: Thu Oct 29, 11:00 am - 12:15 pm (weight 20%)
Final: Mon Dec 14, 9:00 am - 11:00 am (weight 25%)

No make-up exams are given,
except in cases of documented illness or emergencies.
For students with documented special needs, a time extension
can be arranged if requested at least ten days before the exam.
