May I suggest that you use repetition and write down your answers to the questions. For example, if you are have a test or quiz on a specific chapter, put all the questins in random order. One by one, write down your answer to each question. When finished check your answers. Repeat this process for any answers your answered incorrectly. Continue until you have answered all the questions correctly. This study method utalizes the way our brains absorb information. It has been proven, that our memories repond best to this type of stimuli. It may seem boring, but this will bring you success on your test. This formula can be applied for all tests, even end of the year test, which can include everything studied during the school year.
