Helpful – AP World History Exam Prep + Review

I love learning and so, I love this app. I learn interesting, thought provoking things. Thank you! However, it would be wonderful and enlightened to offer the entire information free of charge. Particularly in light of the content here and movement in North America to educate everyone regardless of financial worth and background. Hopeful for an educated nation. Thanx again.
