Hi there!
Thanks for your interest in our free practice exams. The level of difficulty of the problems in these exams is consistent with what you will see on the NCEES Principles and Practice of Engineering Examination. Our practice exam is an 8-hour open-book exam. It contains 40 multiple-choice questions for a 4-hour morning session, and 40 multiple-choice questions for a subsequent 4-hour afternoon session.  Our exams are in accordance with the latest specifications from NCEES, which became effective beginning with the April 2017 examinations.
For mechanical engineering, you must select one of the three exams available:

• Mechanical: Thermal and Fluids Systems
• Mechanical: HVAC and Refrigeration 
• Mechanical: Machine Design and Materials

With the exception of steam tables, everything you need is provided in the downloadable exam booklet (e.g. a psychrometric chart, and by the way, speaking of steam tables, you can download our own for free from our Free Resources page).  Relevant parameters required to solve specific problems (viscosity, thermal conductivity, Young's modulus, friction factors, etc) are provided in the problem statements.

​We will not develop Machine Design and HVAC&R practice exams until NCEES completes the transition to computer based testing (CBT), which is expected to occur within the 2019-2020 timeframe. NCEES recently announced the mechanical engineering PE exam will be a closed-book format CBT test and they will provide (on screen) the only reference allowed. For this reason, we will await until the NCEES exam reference becomes available to craft our practice exams based on their reference book.
