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
