Office Hour

My office hour: MWF 4-5pm at my office (location tentative)

If you are not sure what "office hour" is, it is an opportunity for you to talk to me about the class, seek help in topics you are unsure about, discuss the homework problems you are stuck at. A lot of students tend to be intimidated to talk to the instructor, fearing that they are judged for not knowing the material. The fact is, we are trying to help you succeed, and we do not evaluate student at all during office hours. A student who comes to office hours regularly will generally leave a good impression to the instructor, in contrast to the misbelief that the instructor would think such student is not performing well. So, if you need anything, come to office hours. Seek help soon, rather than later!

Class Format

The class will not be in a traditional "lecture-only" style. I will ask you to actively participate. This includes have you work and talk both as a small group in class, and in front of everyone. See "Reading" in Syllabus.pdf.

Attendance is not part of your grade, but it is required via oral presentation. If I pick a person to present and they are not in class, they get a 0 for the presentation.

Late Join Policy

If you wish to enroll in this class (e.g. you are currently on the waitlist), you should keep up with the class since day 1. In particular, you need to attend all lectures, submit all the homework on time and be present for progress checks.

(IMPORTANT) When you are finally officially enrolled to the class, please read the ''Welcome Message'' on Canvas Announcements, and complete everything it instructs you to do.

Homework

Please read the homework instructions before working on the homework.
