There is no reason for you to take the CPA exam. Second, any experience gained as a tax attorney is not the same as experience gained as a CPA. You have answered a very special calling to attend law school, therefore it is not in your best interest to mix apples and oranges at this critical time. CPA's are completely different from lawyers, including tax lawyers. You are not passionate about a career as a CPA, so you should not take the CPA exam.
