Fundamentals of Engineering (FE)ENVIRONMENTAL CBT Exam Specifications
Effective Beginning with the July 2020 Examinations•The FE exam is a computer-based test (CBT). It is closed book with an electronic reference.

•Examinees have 6 hours to complete the exam, which contains 110 questions. The 6-hour time also
includes a tutorial and an optional scheduled break.

•The FE exam uses both the International System of Units (SI) and the U.S. Customary System(USCS).
