Study Tips for Modern Era & Cold War

1

Group New Deal programs by R: Relief (CCC, WPA, FERA), Recovery (NRA, AAA, TVA), Reform (Social Security, Wagner, SEC, FDIC). The categorization makes 30+ alphabet agencies easier to recall.

2

Build a Cold War timeline card listing the major events in order (Truman Doctrine, Marshall Plan, NATO, Korean War, Cuban Missile Crisis, Vietnam, fall of Berlin Wall). The exam loves chronological reasoning.

3

Memorize the 16th, 17th, 18th, and 19th Amendments together as the Progressive amendments: income tax, direct election of senators, prohibition, women's suffrage. Their clustering is testable.

4

For civil rights, build a card pairing each major event with a federal response (Brown decision → 1957 Civil Rights Act; Birmingham → 1964 Civil Rights Act; Selma → 1965 Voting Rights Act). Causal links earn essay points.
