Communication
Piazza
Piazza is the preferred way to get help, whether from the instructor, TAs, or other students.
- Do not post code or answers to project questions.
- Do not rant.
ELMS
Not Used. Messages sent to keleher on ELMS will not be read.
Email to the instructor as a last resort if neither piazza, office hours, or email to TAs suffices. Include 412 in the subject or I may miss it.
