Policies and Procedures

General Requirements

This class will be conducted in the traditional format of face-to-face lectures. When taking this class, students must:

  • attend the class, as scheduled;
  • actively participate in class work;
  • prepare assigned reading;
  • submit assigned homework;
  • pass all in-class quizzes and the final exam.


The course average will be computed as a weighted sum:

  • 75% – quizzes: pop quizzes will be given in class throughout semester; they will last no more than 20 minutes each and will cover current material;
  • 25% – final exam: final exam will be given at the end of the course; it will cover all topics of the course.

No test grade will be dropped. If a test (i.e. a quiz or the final exam) is missed, then the grade 0 is assigned for that test.

Letter Grade Necessary and Sufficient Conditions
A Course average 90 and above.
B+ Course average 85–89.
B Course average 80–84.
C+ Course average 75–79.
C Course average 70–74.
D+ Course average 65–69.
D Course average 60–64.
F (failed) Course average below 60. The course must be repeated.
FN (failed due to non-attendance) Stopped attending the class without communicating with the instructor. The course must be repeated.
W (withdrawal)

Withdrew officially

The course must be repeated.


Make-up tests will be given only for documented emergencies, and then only at the instructor's discretion and convenience. However, if you have a good reason, please do ask for consideration.

Attendance Policy

The class will be conducted in real time, face-to-face, in the format of a traditional lecture, as scheduled.

The College expects that each student will exercise personal responsibility with regard to class attendance. All students are expected to attend every class session of each course for which they are registered. Students are responsible for all that transpires in class whether or not they are in attendance, even if absences are the result of late registration or add/drop activity at the beginning of a term as permitted by College policy. The College defines excessive absence or lateness as more than the equivalent of one week of class meetings during the semester. Excessive absence or lateness may lead to failure in, or removal from, the course.

Any student who enrolls in this course after the first meeting, regardless of reason, is accountable for all course requirements including assignments and attendance.

Arriving late, leaving early or taking unreasonably long breaks will be recorded as partial absence.

A student may be required to drop or withdraw from a course when, in the judgment of the instructor, absences have been excessive. A student may also be withdrawn from a course by the Associate Dean of Student Services or the Student Conduct Board following a disciplinary hearing for violating the Student Code of Conduct as described in the Student Handbook.

Students are advised to report COVID-positive test results to the Health Services Office via email or phone (631) 851-6709.

A PCR, or a rapid test taken at a facility, or a home test, will all be acceptable.  Students must provide a copy of the test result along with a copy of a photo ID.

Students who miss class for any illness should contact the instructor as soon as possible to discuss reasonable adjustments that might need to be made. When possible, students should contact the instructor before missing class.

Religious Observance

As provided for in New York State Education Law §224-a, student's absence from a class necessitated by religious observance will be deemed an excused absence, with no academic consequences. Students must notify their professor at least one week prior to their absence due to a religious observance. The notification must be made via their College email, or otherwise in writing, Observing students shall be granted reasonable arrangements and/or be permitted a reasonable amount of time to make up missed quizzes, tests, assignments, and activities covered in their absence. Please refer to the Religious Observance Policy for additional information.

Disruptive behaviors, as defined by the Student Handbook, will not be tolerated. In case of violations, the college policy allows the instructor "to remove a student from a class for one class meeting, and, in those cases where the continued presence of the student poses a substantial threat or would be disruptive to the class, request that the Associate Dean of Student Services impose an interim suspension pending a disciplinary hearing."

Academic Integrity

The College's Student Code of Conduct expressly prohibits engaging in any form of academic dishonesty. In case of violations, the college policy allows the instructor to "initiate student conduct action through the Campus Associate Dean of Student Services. The faculty member may impose any of the following penalties: require that the student repeat the assignment or the exam; give the student a failing grade for the assignment or exam; or give the student a failing grade for the course. Should the student believe that s/he has been wrongly or unfairly accused of academic dishonesty, the student shall have the right to pursue the matter though the Course Grade Grievance Procedure."

To learn more about academic integrity, college policies and expectations in this area, and proper ways to avoid possible violations, see the Academic Integrity and Plagiarism Guide.

Once approved for reasonable accommodations, such students will be provided with a letter, describing the specific accommodations. Students must present this letter to each of their professors before accommodations can be provided.

Students who have, or think they may have, a disability are invited to contact Office of Disability Services for a confidential consultation. You can call the Office at (631) 851-6355, contact it via email, or stop by to make an appointment in Caumsett Hall, Lower Level, Room 20.

COVID-19-related Policies

Mandatory Safety Measures

The safety, health, and well-being of students and the College community are Suffolk County Community College's primary concern during the COVID-19 pandemic. Your compliance with these mandatory safety measures will help reduce the risk of on-campus transmission of COVID-19, so that we can convene face-to-face classes and student activities. Failure to comply with the COVID-19 safety measures will result in referral to the Office of the Campus Associate Dean of Student Affairs for potential disciplinary action.

The policies and procedures of this class may need to be updated in course of the semester in response to changing COVID-19 situation or external mandates. For up-to-date College policies and procedures related to COVID-19, please consult Coronavirus (COVID-19) Information. Additional information is available in COVID-19 Vaccination FAQ.

Vaccination Requirements

All students taking this class are required to provide the College with documentation verifying their vaccination status.

Students may apply for an exemption from the mandatory vaccination requirement for medical or religious reasons using the process outlined here; exemptions are not guaranteed. 


Currently, the College is following a "Mask Optional" policy. Students are not required to wear masks in the classroom, nor in any College buildings. Masking continues to be an option for all members of our community. Students are encouraged to wear a mask should they wish to do so. The College will not tolerate harassment of any member of our community for their choice to wear a mask. Furthermore, wearing a well-fitted mask is required in the following circumstances:

  1. If you were in close contact with someone with COVID-19, you must wear a well-fitting mask for 10 days from the date of your close contact with such an individual. It is strongly suggested that you get tested at least 5 days after exposure.
  2. If you test positive for COVID-19, and have completed your required 5 days of isolation, upon your return to campus, you must wear a well-fitting mask for the next 5 days.

Course Modality Changes

The College reserves the right to change the masking protocols described above, the course modality or other COVID-19 rules and requirements based on the local COVID-19 rates, or as required by New York State, SUNY, and the Suffolk County Department of Health Services. Students who cannot wear a face mask due to a medical condition or disability, or who are unable to remove a mask without assistance, should seek an accommodation through the Office of Disability Services.
