Below are the NCEES category specifications for exam coverage.

Effective ** UNTIL **July 1st, 2020, these are the categories and subcategories specified by the NCEES that this discipline will cover. It includes an estimate of the number of questions you will see on the official exam for each category. PrepFE provides hundreds of questions in proportional amounts to the official exam.

*For the upcoming categories that are effective as of July 1st, 2020, please see the categories here. *
