Whether you're in APUSH or U.S. History 1877-present, there are a couple of things you should know and do.
- Read often. APUSH you have the books you need to read for class. U.S. History you need to find nonfiction books and read them.
- Practice Writing. Doesn't really matter right now what you do, but at least practice writing a letter to a character from the book you're reading and ask an unanswered question.
- Get familiar with major historical events. Reconstruction, Progressive Movement, WWI, the roaring 20s, The Great Depression, WWII, The Cold War, Vietnam, Korean Conflict, The Civil Rights Movement, an the Gulf War, just to name a few.
