Tentative course schedule - CH201 - Summer 2017

Assigned readings and videos for preparing for lectures:

  • DCH: Readings from Harris 5th edition; excerpts are posted on Blackboard.
  • LM: Lab manual
  • WC: Writing chapter at the end of the lab manual
  • Links are to helpful review videos that you should watch before lecture

Make sure to keep up with your preparation by reading the selected pages (in the lab manual and DCH), and watching the short videos, ahead of the lectures.
