"I need help with my homework!"

  • There is probably someone in the IPL today, or maybe Zorah has office hours. If so, go see them.
  • Check the message board; your question may have been answered there.
  • Read the relevant chapters and sections of the textbook, or watch the textbook "online portal" videos if you have access to them.
  • Look at the in-class lecture examples.
  • Look at this week's section handout problems and their solutions.
  • Start early! We get swamped the day assignments are due.
  • Don't panic. You have late days, and even if you run out, it is only -2 points for each additional day late.
