The second strategy I will discuss today is the strategy of outside research. If you want to memorize things, it's good to know a lot about them. Research more about the things you are confused on or have trouble remembering. There are many books and textbooks written in the library that could aid you in your search. That way, when you hear a familiar phrase, you'll think of what you learned from your research, and not have to guess about the answer. This method takes more time than others, so if you're short on time, this might not be the best approach for you.
