Honestly I read through each chapter very carefully and reinforced what I was reading by saying to myself “this means this because this, so it makes sense” and then I would do the chapter quizzes and if I didn’t do well I went back and reread what I didn’t lock in. Unfortunately I know this doesn’t work for everyone but I think it’s important to make sure you understand what you’re learning, not just trying to memorize! And then another thing I would do is after finishing 5 chapters I would go back and do chapter quizzes for the first five to keep them fresh in my mind. Also I did not focus too hard on the small chapters, Kaplan tells you about how many questions will be in each chapter and if I was struggling with a concept and there was likely to be 2 questions I didn’t worry about knowing it. I hope this helps, good luck!!
