I say just hit the question bank. I did literally every single Schweser qBank ethics question and scored 100% on one of my mocks, and I ended up over 90% in the real thing, which allowed me some breathing room on my weaker topics. Ethics is a topic where there is a certain amount where you just have to remember stuff, but a lot of it is applying rules to situations, which means the only way is through practice and recognizing patterns. It’s not a case of just reading the material over and over again. Eventually you’ll just get a feel for it based off repetition.
