33 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.
Read the question carefully before looking at the choices. AP Euro Unit 9 questions often hinge on distinguishing NATO from the Warsaw Pact, or the fall of the Berlin Wall from the collapse of the USSR: don't assume based on a single keyword.
Eliminate before guessing. Distractors often include true statements about a different event or a different unit's content. Cross out anything that doesn't directly answer the question asked.
Connect events to themes. If a question is about decolonization, the EU, or Gorbachev's reforms, think about which course theme (SIP, INT, ECD, NEI) it connects to; that's usually the key to the right answer.
Read the explanations even when you got it right. Each one teaches a small fact that often returns in a different form on the exam.
