Tardiness / other disruptions. If a student is late to the class for more than 10 (ten) minutes, (s)he is not allowed to enter and disturb the class. However, this student is able to enter the second double hours without delaying. Exams In order to be excused from the exam, the student must contact the dean and the instructor before the exam. Excuse will not be granted for social activities such as trips, cruises and sporting events (unless you are participating). The exams will all be cumulative. Most of the questions on each exam will be taken from the chapters covered since the last exam. But some will come from the earlier chapters. In general the coverage will reflect the amount of the time spend in class on the different chapters. Withdrawal (pass / fail) This course strictly follows grading policy of the School of Engineering and Applied Sciences. Thus, a student is normally expected to achieve a mark of at least 60% to pass. In this case of failure, he/she will be referred or required to repeat the course the following term or year. Cheating / plagiarism Cheating or other plagiarism during midterm and final examinations will lead to paper cancellation. In case, the student will automatically get 0 (zero), without any considerations. Professional behaviour guidelines The student shall behave in the way to create favorable academic and professional environment during the class hours. Unauthorized discussions and unethical behavior are strictly prohibited. For successful completion of the course, the students shall take an active part during the class time, raising questions and involving others to discussions. Learning and Teaching Methods This course considers active learning process rather than passive one. Week Topic 1 1 2 3 2 3 Tentative Schedule Topics Some Fundamental Chemical concepts (1-8) i.
