Audio readings of every chapter! My suggestion is to play these at X1.25 speed and pausing when necessary. Using headphones will help keep you focused.
PRACTICE QUIZZES. True, they are for a different textbook, BUT U.S. History is U.S. History...you feel?
SUGGESTED: Provides detailed outlines for each chapter. As you read the book, you can add your own notes to the outlines.
PRINTABLE outlines for each chapter.
FINALLY, if you need some funny, fast-paced, and informational videos...I present to you John Green.
