The best way I have found through trial and error is to first create flashcards of those quotes. This lets you break down the many quotes you may need to remember into more manageable pieces of information. Then, as silly as it seems, is to act out the quotes as the characters, preferably in the most weird or wacky way possible. By doing this you are more likely to remember the silly action or way you said the quote and thus the quote itself.However, everyone learns in different ways. This method has worked for me before, but the best way to know is to simply try them all and see. Finding a method of study early on will greatly help you later!
