I'm somewhat self-studying (taking a regular World History class, although it doesn't cover nearly as much material as AP).
I'm using a combination of Barron's and
PR -- Barron's is more extensive and has more info (maybe a bit excessive), while
PR seemed too light to cover up all the info. Highlight/mark up Barron's like crazy. I think it's doable, or maybe I just really like history.

Props to you, and good luck!
