For level 1, many people suggest to read ethics once early (and do some practice problems), and then to focus on all other areas except ethics until the day before the exam. That Friday before the exam, you re-read ethics (and do a few more practice problems). The idea being, this will be enough prep for a candidate to nail this section of the exam.
I found that this approach worked for me, and I feel confident that I scored >90% on the exam.
My question: For level 2, is this approach commonly used, and do people find that it works?
Thanks
