A course about connections
The multiple-choice questions come in sets around a source, and the document-based question and long essay reward comparison, causation and change over time. AP World asks, again and again, how something in one place changed something somewhere else.
That's what edgi's Map is for. Collect the Silk Road and the Map shows it leading to the Mongol Empire, cultural diffusion, the Maritime Silk Road and globalization: Unit 2 to Unit 9 in one step. Mansa Musa leads to Timbuktu, the hajj, Ibn Battuta and the transatlantic slave trade. Zheng He leads to the Ming dynasty and the Age of Discovery, which is the comparison essay about why China's fleets turned back and Europe's didn't, laid out in three cards.
A stack of flashcards gives you facts that each stand alone. A Map gives you the arguments. Here's one that ties Unit 7 to Unit 9, the deal that ran the world's money after 1944:

Bretton Woods system
From 1944, every money was tied to the dollar and the dollar to gold, until there were far too many dollars and Nixon cut the tie.
Make your own AP World review
Type what you need and edgi makes it. "Quiz me on Unit 6" gets you a 20-question quiz. "Quiz me on the Meiji Restoration versus the Qing response to the West" gets you one on that exact comparison. "Make me an explainer on why the Columbian Exchange mattered for Afro-Eurasia" gets you a few minutes of audio, screen off. "Teach me the Scramble for Africa" gets you a Lesson that walks you through it, has you answer as you go and ends with its card. It all lands on your Map next to what it connects to.
The exam opens with 55 multiple-choice questions in 55 minutes and three short answers, then the document-based question and one long essay. A few Lessons a day from September is how you walk in with the whole map in your head.
Eight centuries, a few minutes a day
Nobody crams eight centuries the week before the exam. edgi makes the daily habit the easy part: one Lesson keeps your streak, a widget on your home screen shows it, every Lesson earns a card, cards turn foil and then gold as you come back to them, and every Set has a finish line. Your Map fills in region by region, so you can see where your gaps are.
