Plumbing/Heating Mock Exam Supplement (2020 NEC)

120 realistic sample examination questions and answers to prepare you for your Plumbing and Heating Electrical Exam. 


We recommend that P/H exam takers purchase this mock exam in addition to our normal limited/unlimited mock exam.

These proprietary questions — derived from real-world exams — test your code knowledge and exam readiness before test day. They'll familiarize you with the question styles, formats, and classifications you'll see on the actual Plumbing/Heating exam so you know where you stand before you sit for it.

Sample tests cover all material on the exam, including project management. This Q&A book works as a companion to our Exam Preparation Workshops or as a standalone tool when you want to gauge whether you're ready to pass.

According to thousands of JCR students who have used this material, the score you make on these sample tests will be within a point or two of your actual exam score.
