CLASS REQUIREMENTS:

​

Exams

 

This course requires three major exams (Midterm and Final). Schedule of the said exams will be announced ahead of time.

 

Quizzes, Assignments, Board Works, Seat Works, Oral Recitation

 

Occasional quizzes will be given as one of the requirements of this course. It is the instructor’s discretion if his/her quizzes are announced or not and that would include topics that are recently discussed in the class. No make-up quiz for any missed quizzes/assignments (regardless if it is valid absences or not), and for any missed quizzes/assignments, a grade/score of zero will be recorded. During class time, the instructor may give seat work and board work or conduct an oral recitation which may or may not be graded (instructor’s discretion).

​

Class Policies

 

  1. A student with 3 consecutive unexcused absences will be DROPPED from the class.

  2. The students are required to take all the three major exams on the set scheduled emanation period (date, time and room). Arrangements must be made to the instructor/s concerned if the student will take the exam ahead of time (set scheduled day) but not after the scheduled day except for special cases (to be examined by the Division). It is the student’s responsibility to notify his/her instructor if he/she missed an exam. The instructor concerned will evaluate the validity of his/her reasons if the said student is eligible of taking a special exam.

  3. There will be no make-up exams (major exams) for an unexcused absences and a grade of zero will be recorded. Make-up exams will be allowed only for excused absences. If the student missed the exam due to school activities, proper documentation must be presented.

  4. Academic dishonesty will not be tolerated. Any student found to have participated in any activities related to academic fraudulence will receive a grade of “5.0” in the course, and maybe subject to further disciplinary action. The State Institute’s Code of Conduct prohibits students from committing the following acts of academic dishonesty: academic fraud, copying or allowing one’s work to be copied, fabrication/falsification, sabotage of other’s work, substitution (e.g. taking an exam for someone else) among others.

  5. Students are encouraged to utilize the instructor’s consultation time (refer to your instructor’s consultation schedule).

  6. Passing rate is 50%.
