Chapters?

What chapters are going to be covered on the exam? does any one know? I know 22 and 24, but is 9 going to be on there too?

As far as I know, everything we've gone over in class will be on the exam. So, all three chapters are up for grabs, I think.

Not only will the thee three chapters will be on the exam, but stuff we didn't cover in class will also be on the exam.

There should be questions about our labs on the exam!

There should be questions in the book that we do not cover in class or lab that will be on exam!!
