Textbook
• You’ll have to read it
• Homework tells you what
• The lecture does not repeat the book
• Typically the reading is ahead of the lecture
• Enables meaningful in-class discussions

Laboratories
• You must complete all labs to pass the course!
• 3 hour lab sessions
– Do prelabs to finish on time
– Makeup labs if you miss one or do not finish
• Work in groups of two
– Not three (or four or …)
– One feels lonely
• Sign up for lab NOW
– Mike to mike
