OTHER COURSE POLICIES
Title Description
Attendance
According to CHED policy, total number of absences by the students should not be more than 20% of the total number of meetings or 15 hours for this course.Student incurring more than 15 hours of unexcused absences automatically gets a failing grade regardless of class standing.
Language of Instruction
Lectures, discussion, and documentation will be in English. Written and spoken work may receive a lower mark if it is, in the opinion of the instructor, deficient in English.
Honor, Dress and Grooming Codes
All of us have been instructed on the Dress and Grooming Codes of the Institute. We have all committed to obey and sustain these codes. It will be expected in this class that each of us will honor the commitments that we have made. For this course the Honor Code is that there will be no plagiarizing on written work and no cheating on exams. Proper citation must be given to authors whose works were used in the process of developing instructional materials and learning in this course. If a student is caught cheating on an exam, he or she will be given zero mark for the exam. If a student is caught cheating twice, the student will be referred to the Prefect of Student Affairs and be given a failing grade.
Consultation Schedule
Consultation schedules with the Professor are posted outside the ChE-Chm Faculty room and in the School’s web-page (
http://che-chm.mapua.edu.ph ). It is recommended that the student first set an appointment to confirm the instructor’s availability.
Examination
There will be 2 examinations equivalent to 20% each. Students are allowed to take each examination up to two times should they fail to score at least 80% in each attempt. Every time a student fails, He/She will be required to attend a clinic class prior to the next examination attempt. If he/she fails to score at least 80% in the second attempt, the highest score that he/she obtained in the two attempts will be recorded as his/her score for that examination.
Worksheet
Students are required to answer all worksheet assigned per topic as scheduled. The total score for the worksheets will be
equivalent to one examination, that is 20%. OTHER REFERENCES
