The schedule includes both the Livestock Medicine I and Large Animal Surgery I lecture dates/times to help keep track of the “who” and “when”.

Grades for this course will be based on 2 assignments, a midterm exam and a final exam. The assignments are in the Weekly Lessons they are untimed but must be completed by the due date in the Weekly Lessons. The due dates will also be posted on the calendar.

Optional (ungraded) study materials will be posted in the Weekly Lessons.

The grading scale for this course is:

Assessments using ExamSoft and ExamMonitor: A grade reduction of 5% will be applied to that exam if students do not observe the parameters listed in the Assessment Policy for Students.

It is highly recommended to look at the plan at the start of each week in the Sakai Weekly Lessons. Links to all the materials for the week/topic will be provided there. Panopto videos will be linked by the end of the day. Reminders and due dates will be listed in the Weekly Lessons and in the calendar.

Additional individual or group office hours can be made if needed. If a student feels they are falling behind or their grades are inadequate, they should arrange a meeting with their academic advisor as well as someone from the DES office.

For the grading of examinations, the slides and notes, lecture handouts, and the statements made during lecture will be considered correct. Your correction of the notes and information provided is encouraged. However, information found which contradicts these sources must be brought to the attention of the instructor prior to an examination. The source will be evaluated and if indicated, corrections made (to the entire class). Do not expect to receive credit for information that contradicts these sources unless this procedure is followed.

You are expected to attend and participate in classes and keep up with the weekly tasks. If you are having difficulty with the subject matter, are unsure of terminology, etc. please post in the Sakai Forum, email me, ask a classmate, or check reputable sources on the internet.

Assignment extensions must be requested BEFORE the due date. Valid reasons are posted in the student manual.

Students are expected to conduct themselves in an appropriate professional manner in their interactions with lecturers and fellow students. Please be respectful, courteous and open to other people’s opinions. Cell phones should be switched off or silenced during lectures. Please arrive on time for lectures.

Students are expected to be available during the standard 8:30am- 5:20pm AST school day, to attend, engage with in-person/online content, and participate in all classes and clinical rotations for which they have registered. Employment is not an excusable absence.

Although attendance, engagement, and participation may not be recorded at every academic activity, attendance, engagement, and participation is graded for mandatory sessions. Students’ lack of attendance, engagement, and participation may adversely affect their academic status as specified in the grading policy.

If failure to attend, engage, or participate in individual classes, examinations, and online activities, or from the University itself is anticipated, or occurs spontaneously due to illness or other extenuating circumstances, proper notification procedures must be followed.

You must notify the instructor BEFORE the due date to request an extension for an assignment. Approval requires a valid reason as posted in the student manual. Students who fail to attend an examination (Sakai quiz/test or Examsoft) or submit an assignment by the deadline without a valid reason (see student manual: SGUSVM POLICY ON AN EXCUSED ABSENCE (EA) FOR STUDENTS) will receive a score of “0” points for the quiz, examination, or assignment.

Students who have technical issues during the examination MUST inform the Course Director (Dr. Stacey Byers, sbyers1@sgu.edu) and IT (tellexaminationservices@sgu.edu OR support@sgu.edu OR call 1- 631-665-8500 ext. 4444 (US, NU, International) OR 1-473-439-2000 ext. 4444 (Grenada), AND Dean of Students (DOS@sgu.edu) during the open period for the examination. Failure to do so immediately will result in the student receiving the highest score recorded at the time, but NOT being eligible to take a completion examination.

Scheduling of examinations (regular, re-sit, completion, comprehensive, or exemption) is at the discretion of the University.

All students are responsible for knowing and complying with the University’s Code of Conduct and the guidelines. Students must read and then sign the Honor Code statement at the start of examinations to indicate that they will comply with the University Code of Conduct.
