<p>To be specific, Barrons AP Human Geography and Princeton AP Human Geography. THANKS! :D</p>
<p>It depends on the person. Some people just skim through and pick up a lot of info, while others read meticulously to absorb the details. You’d be the best judge.</p>
<p>I have been doing a combination of both of those methods. I tried reading through every word once, and then skimmed through a second time. It seems to work well, since the critical information seems to stick out once you’ve already been through it once and you’re looking for just the critical stuff on the second pass.</p>
