Do you need help with something? Which resource you should use
depends on the nature of your problem. For
questions about
the subject matter, try looking to see if a similar question
has already been asked on
Piazza
first; and if you can't find an answer, ask a new question there.
This will allow us to prepare (and refine) one authoritative answer to
each question, and may keep you from having to wait for an email
reply!
