Regarding Posting of Assignments' Solutions/Implementations
TA Room/Office Hours

Office hours get extremely busy the day before an assignment deadline and you may not get the help you need to do the large number of students looking for help. Please do not wait to start your assignments so you have an opportunity to address any concerns during office hours.


You need to keep backups of your assignments as you develop them. No extensions will be granted because you accidentally erased your assignment. Feel free to use the submit server as a backup tool by submitting often.


We will be using (Piazza) for class communication. Your instructor will register you using the e-mail address you have in the school system.

Academic Integrity

Note that academic dishonesty includes not only cheating, fabrication, and plagiarism, but also includes helping other students commit acts of academic dishonesty by allowing them to obtain copies of your work. In short, all submitted work must be your own. Cases of academic dishonesty will be pursued to the fullest extent possible as stipulated by the Office of Student Conduct.

The Computer Science Department takes academic integrity seriously. Information on how the the department views and handle academic integrity matters can be found at Academic Integrity. Additional information can be found in the section titled "Academic Integrity" at Course Related Policies.
