Princeton Review enough or need more?

<p>So i tried reading that consiladated book sugggestion thread and everyone was either going for the barrons or the pr for world history.
my question is which one is better for self studying.i have the pr and want to get a 5 and am willing to read both but is it necessary?</p>

<p>has anyone here self studied world history and gotten a 5? has anyone only read pr for preperation and got a 5? barrons only? both?if so please tell me how you did it?</p>

<p>I was wondering the same thing, so i hope someone here knows the answer !</p>
