NEW! Each of the methods group exams includes a few questions that require some calculations. The questions provide all the data needed for the calculations which are derived directly from the equations specified in the relevant methods. For either exam format (i.e., in-person or LOP), the candidate may NOT use a personal calculator, mobile/smart phone, or other personal electronic calculations device during the exam session. This revised policy for in-person exams will go into effect as of June 5, 2023.  After that time, the candidate must use the multi functional calculator provided by the proctor for in-person exam sessions.
