There is a theory about types of personalities, and the Meyers Briggs chart summarizes the types. You should be able to pick yourself out from just looking at the chart which has 16 personality types. Google it and you can even find some free quizzes that are fun. If you are an accountant and want to be a CPA you will either most likely be an INTJ (introvert, innovative, thinking, judging) or ISTJ ( introvert, sensing, thinking, judging). Granted there are a few extroverts after all we need to have partners and directors whereas introverts tend to make good Controllers. In other words, the CPA occupation tends to employ thinking (how we make decisions) and judging (how we prefer to think about rules) personalities with either a sensing or intuitive preference for processing information. Being able to differentiate how you process information will have impact on how you prepare and review for the exam.
