AP Econ Prep Books

Hey,
I’ve looked over book recommendation threads on here and have slimmed it down a choice between PR and 5 steps to a 5? I can get both, but I don’t want to spend the extra money if it isn’t necessary since I’m taking a decent amount of AP tests this year.
My class uses Economics: Principles, Problems, and Policies (16th edition) by McConnell and Brue if that has any influence whatsoever.
I’ve used PR, and I liked the layout but have no experience with 5 steps.</p>

Thanks for your help!</p>

Get 5 steps it simplifies your study strategy</p>

hmm…how so?</p>
