Organize your notes chronologically. It goes without saying that the field of history comprises many events that took place in a certain chronological order. Maintaining that chronology in the notes that you take both in class and while reading will help you organize the information you receive. Always jot down the date of events in your notes and try to keep things sequential. For example, if you’re studying the Cold War, organize major events like the Manhattan Project, the Cuban Missile Crisis, and the fall of the Berlin Wall in the order in which they occurred. Use several resources to ensure the accuracy of your historic research.
