Grading & Policies :
Grade are not given but earned. Your grade is determined by your performance on the learning assessments and is assigned individually and fairly.
Based on: Weekly Quizzes 25% + Elevator-pitch 5% (0% if opt out) + Homework 20%+ Mid-term 30% (=15%x2) + Final Exam 20%
Know your rights!
Please visit for the Office of Undergraduate Studies’ full list of campus-wide policies, including: Academic integrity; Attendance and excused absences; Student and instructor conduct; Grades and appeals; Accessibility and accommodations; Copyright and intellectual Property.
If you wish to request special accommodations, please contact the instructor within the first two weeks of the semester.
Get some help!
Taking personal responsibility for you own learning means acknowledging when your performance does not match your goals and doing something about it. You are encouraged to visit to learn more about the wide range of campus resources available to you.
Everyone can use some help sharpen their communication skills (and improving their grade) by visiting and schedule an appointment with the campus Writing Center.
If you just need someone to talk to, visit Everything noted here is free, and everyone needs help… all you have to do is ask for it.
No late homework will be accepted without prior arrangement. Late homework may be accepted with reduced points up to 2 times at reduced points [Same day by 5pm - 70% ; Next day by 5pm - 30%]
Use of external references should be cited.
Students may study together and discuss problems in a general way to improve understanding, but they are individually responsible for their homework. No copying is allowed.
Students with Disability
Students who require special examination conditions must register with the Office of the Disabled Students Service (DSS).
Documentation must be provided to me and discussed within the first week of classes, and paper forms must be filled and provided before every exam.
Absence and Lateness
From official reasons: The student must provide an official letter/paperwork and get approval by the instructor in one week advance for absence or lateness from official reasons.
Due to illness: First and foremost, please do take care and get well. To make arrangement for the missed activities, the student must obtain a note from a doctor or from the health center documenting your illness with the dates clearly specified. Notes from the parents, student himself/herself, or a friend will not be accepted. The student should also email the instructor as soon as possible.
