Grading: Class attendance is required. There will be three tests, a final exam, in class homework and daily quizzes (short
video view verification.)
Pop quizzes can occur at any time, however, they will occur whenever the instructor deems that the class is not prepared
to start on time, reading a newspaper, socializing or otherwise being rude, disrespectful or disruptive during class.
Any student will receive a zero for that pop quiz and any student responsible for multiple pop quizzes will, at the
instructor’s discretion, receive a zero for their overall pop quiz score.
Each pop quiz will count 2% of the overall score.
The tests will be given in evenings as part of a combined help session/test starting at 7:00 PM.

An overall test score, T, between 0 and 100, will be calculated for each student as shown below.
T=
(0.1TL + 0.2TM + 0.2TH + 0.25TFE )
0.75
Where TL, TM and TH represent the Lowest, Middle and Highest test scores for each student and TFE is the final
exam score.
The score, S, for the course will be calculated as follows assuming that HW represents the overall homework
score.
If HW>T then S = 0.05Daily + 0.20HW + 0.75T
Otherwise S = 0.05Daily + (0.20 + 0.002(T − HW ))HW + (0.75 − 0.002(T − HW ))T
An overall score, OA, will be tabulated for each student based on the pop quiz score, Q, the number of pop
quizzes, N, along with the score, S, according to the formula below
OA = S (1 − 0.02 N ) + Q (0.02 N )
and grades will be assigned based on the table shown below.

Academic Honesty: As a result of completing the registration form at the University of Florida, every student has signed the following statement: "I understand the
University of Florida expects its students to be honest in all their academic work. I agree to adhere to this commitment to academic honesty, and understand that my
failure to comply with this commitment may result in disciplinary action, up to and including expulsion from the university."
Software Use: All faculty, staff and students of the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so
can lead to monetary damages and/or criminal penalties for the individual violator. Such violations are also against University policies and rules, and disciplinary action
will be taken as appropriate.
Students with Disabilities: Students with disabilities requesting accommodations should first register with the Disability Resource Center (352-392-8565,
www.dso.ufl.edu/drc/) by providing appropriate documentation. Once registered, students will receive an accommodation letter which must be presented to the
instructor when requesting accommodation. Students with disabilities should follow this procedure as early as possible in the semester.”
UF Grading Policy: Details may be found at https://catalog.ufl.edu/ugrad/current/regulations/info/grades.aspx
Student Evaluations: Students are expected to provide feedback on the quality of instruction in this course by completing online evaluations at
https://evaluations.ufl.edu. Evaluations are typically open during the last two or three weeks of the semester, but students will be given specific times when they are
open. Summary results of these assessments are available to students at https://evaluations.ufl.edu/results/.”
University of Florida Counseling Services: Resources are available on campus for students having problems
or lacking clear career and academic goals which interfere with their academic performance. These resources
include:
1. University Counseling Center, 301 Peabody Hall, 392-1575, personal and career counseling.
2. Student Mental Health, Student Health Care Center, 392-1171, for personal counseling.
3. Sexual Assault Recovery Services (SARS), Student Health Care Center, 392-1161, for sexual assault counseling.
4. Career Resource Center, Reitz Union, 392-1601, career development
