Sections in the book that will be useful:
Chapter 5: Sections 1, 2, 6

material on sets from chapter 3.
How to study:
First, flip through my notes, making sure you understand the
examples presented. Look at the past couple homework
solutions, and also look at Lang’s previous homework
questions on this material. Practice these problems. Finally,
flip through the book to make sure you understand what is in
each of the sections I mentioned above. Keep in mind that I
may not have covered everything in these sections.
