Common mistakes to avoid
Questions where students often pick the tempting wrong answer — make sure you know the right one:
What was the outcome of the Vietnam War?✗ The USA won a clear victory. ✓ The USA withdrew and the North unified Vietnam in 1975.
Why did the USA struggle in Vietnam?✗ Because its army was tiny. ✓ Guerrilla tactics, difficult terrain and limited local support made it unwinnable.
What caused the Cold War?✗ Stalin started it by invading Eastern Europe after the war. ✓ Ideological incompatibility plus mutual suspicion after WWII — disputes over Eastern Europe, the atomic bomb, and broken wartime agreements.
How did the feudal system work in Norman England?✗ Feudalism meant peasants were slaves owned by the king. ✓ The king granted land to tenants-in-chief in return for knight service; they in turn enfeoffed knights who held land in return for military service to their lord.
What were the Wars of the Roses really about?✗ The whole country was at war for thirty continuous years. ✓ Dynastic conflict between rival branches of the Plantagenets (Lancaster and York) over the throne, intensified by weak kingship under Henry VI and noble factionalism.
