@ElvenRanger: No problem - good luck!
"So Barrons is sufficient? Do I even need to read the Myers textbook? I'm self-studying but I want to be prepared for my other AP's too."
Barron's is all you need - it covers nearly all the AP exam topics (95+%). It will probably be much easier to use Barron's as it focuses on preparation specifically for the AP Psych exam, whereas the Myer's book has much more detail and much less emphasis on the AP psych exam topics. Only buy the Myers book if you very interested in AP psych and want to learn more.
@seabasstiano: Yes! Many people start 1-2 months before the exam, so you're still pretty early.
