AP Macro Textbook: Mcconnell Brue vs. Mankiw

<p>I'm planning on self-studying for AP Macro this year and want to prepare over the summer before the school year starts. I've searched online for the reviews of econ textbooks and found that most people use Brue or Mankiw, but I'm still not sure which textbook I should use.</p>

<p>My question is: Should I get Principles of Economics by Brue or Principles of Macroeconomics by Mankiw?</p>
