FE Chemical

The latest NCEES specifications with category and topics.

Effective July 1st, 2020, these are the categories and subcategories specified by the NCEES that this discipline covers. 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 the prior categories and topics that were discontinued at the end of June, 2020, please see the categories here.
