Grade assignment may change from what is indicated above by a curve, but grades will only
be curved upwards never downwards. Thus, a curve will never hurt you and may help you.
A+ grades will only be assigned to students who earn a 97% or above before any potential
average curve is awarded at the end of the semester.
Exams:
The exam dates are listed below. Put them in your calendar immediately because there
are no makeup exams and very few acceptable excuses for missing one. Acceptable excuses
include a death in the family, a University-sponsored event or excursion, or a serious illness
documented by a doctor. Acceptable excuses must be approved before the scheduled exam
date. Exams are all closed-book, closed-note, and closed-friend/neighbor. You may bring a
calculator to the exam; you may not use your cell phones as a calculator. You must bring a
red scantron sheet purchased from the UNCG bookstore to each exam. Please note that the
final exam will be given on the date scheduled by the University.

Homework Assignments:
There are approximately 9 graded homework assignments, administered through MyStatLab.
All assignments are due by 11:59 pm on the evening of the stated deadline. Late submissions
will be accepted for 48 hours after the deadline but will be penalized by 10% for each
day the assignment is late.
I will drop your lowest homework score before calculating your homework average. The
remaining assignments will receive equal weight in your homework grade.
Extra Credit:
You can earn up to 8 extra credit points (percentage points) on each of the three exams.
Extra credit points are earned by correctly answering Quiz questions administered through
MyStatLab. For each quiz question answered correctly, you earn 0.1 percentage points which
will be added to the relevant exam score. Each exam will have two or four quizzes leading
up to it, and quizzes must be completed at the latest 48 hours before the exam.
(For example, correctly answered questions on Quiz 1, Quiz 2, Quiz 3 and Quiz 4 will earn
you extra credit points towards Exam I. Four quizzes must be completed before 6:00 pm on
Sunday, February 15th.)
• Attendance: You are allowed to miss at most 2 classes during the semester. After 2
missed classes, I will deduct 3 percentage points from your course grade for each class
you miss. I reserve the right to count you as absent if you are late to class.
The University’s attendance policy can be read here:

• Academic Integrity Policy: Students are expected to know and abide by the Honor
Code in all matters pertaining to this course. Violations of this code will be pursued
in accordance with the code.

Additional Requests:
• Do not talk to your neighbors during class. It distracts the students around you, and
it distracts me. It will not be tolerated. If you talk during class I reserve the right to
ask you to leave the room.
• I know about the parking problems on campus and am sympathetic, but I do request
that you be on time.
• Please make sure that all cell phones are shut off during lecture. DO NOT answer
calls/text messages during class. If I see you texting, I reserve the right to ask you to
leave the room.
• I encourage you to work together on assignments, although every student is responsible
for submitting his/her own answers to each graded assignment in order to receive credit.
• When you begin to feel lost, BE PROACTIVE!! I am more than happy to answer
questions during lecture.
• I want to make it known up front that I expect you to spend a minimum of 5 hours
per week reading, reviewing, and completing homework assignments outside of class. If
this is not feasible for you given your other time constraints, then perhaps this is not
the course for you.
