Please direct all course-related questions to Piazza (or go to office hours). If you want to discuss other topics or have personal/team issues that can and should only be handled by a professor, please email me directly (ys3kz).

Academic Integrity

Please also read the course syllabus carefully for additional information

No plagiarism

You must cite any and every source you consult, other than those explicitly provided by the course itself. This includes talking with a friend/classmate or looking at a website/book. If you're unsure, please ask us. We run all submissions through a plagiarism checker by default.

Write your own code and DO NOT share your code

All assignments are individual work and there is no collaboration allowed. That means you should not push it to GitHub (or any other site), send a copy to anyone, turn your screen to your neighbor, code up solutions together, etc. It is ok to discuss with classmates, but please include the names of students whom you've discussed with.

Consequences of dishonesty

Penalties may be up to and including a failing grade (F) in the course, independent of and in addition to the operations of the Honor Code.
