Final Exam:

There will be a comprehensive final exam at the end of the semester. The final exam cannot be rescheduled. Missing the final exam will result in an F or WU or INC grade for this class unless otherwise discussed. An INC (incomplete) grade may be given by the discretion of your professor if all your other course work has a passing grade. In the case of an INC grade, you need to clear it as soon as possible by making the necessary arrangements with your professor.

Attendance:

Attendance will be recorded during each class session. Six or more unauthorized absences will result in a WU grade. In general, the only acceptable excuses for missing class (including exams) are serious illness, family/personal emergency, or religious observance. Appropriate documentation must be presented to authorize an absence.

Academic Integrity:

Students are expected to uphold the CUNY Policy on Academic Integrity. Cheating on exams will result in failures, at minimum. For details on the school’s policy on this, see the Academic Integrity section of the Student Handbook.

Student Accessibility:

Qualified students with disabilities will be provided reasonable academic accommodations if determined eligible by the Center for Student Accessibility. Prior to granting disability accommodations in this course, the instructor must receive written verification of student’s eligibility from the Center for Student Accessibility. It is the student’s responsibility to initiate contact with the Center for Student Accessibility staff and to follow the established procedures for having the accommodation notice sent to the instructor.
