Class notes and Handouts:
Students must take notes in the class. Derivations and problems would be copied from the board as the instructor writes while the student should note down important points as the instructor orally delivers the lecture. This body of material would form the most important asset of the student for exam preparation and in obtaining good grades.
Additional study material supplementing the class notes is the textbook. The student must always inculcate the habit of book reading for deepening and strengthening the concepts gained in the class.
Attendance Policy:
Class attendance is mandatory. You are expected to be present in all classes. The students having their attendance less than 75% will not be allowed to appear in the exam and will be awarded an “F” grade henceforth.
Homework Policy:
Quizzes:
These will be held promptly on the designated day. They will cover the material taught in the previous weeks. Late arrival or nonattendance without a legitimate excuse will mean that you are ineligible to take that quiz.
Academic Dishonesty:
The UOS is an academic community whose purpose is the pursuit of knowledge and the development of its graduates as leading experts in their academic disciplines. All members of this community must be committed to the principles of truth and academic honesty. Academic dishonesty includes the following acts committed knowingly or intentionally by the student:
Students who have committed an act of academic dishonesty are subject to one or more of the following penalties:
Records of incidents of academic dishonesty will be kept on file at the Wah Engineering College and may be reported to the student’s guardian and sponsor.
Students who are in doubt about whether certain academic activities are honest or not should discuss the matter with the course instructor or consult the WEC policy on academic integrity.
Disclaimer:
The instructor reserves the right to change, and adjust the policies and class schedules at any time during the semester.
