I know this is an old post but in reality... Everybody should start their PREP with a solid memorization process of FA assuming that you really learn the material the first time. There is no such thing as re-learning... if you really learned it the first time you will memorize it literally 100X faster compared to a new topic. You can probably hit the 230's all depends on the confidence and attitude you have during your memorization phase. The ideal move is to apply this knowledge with UW and add more information to your brain with its explanations.
