Updated for the new July 2020 FE Exam Topics

Environmental

Below are the NCEES category specifications for exam coverage.

Effective 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. We've covered the specification changes in this blog post. PrepFE provides hundreds of questions in proportional amounts to the official exam.

For current categories that are effective until July 1st, 2020, please see the categories here.
