Practice exam
This practice exam draws 60 questions from a 350-question bank covering all 14 lessons, with each of the 5 topic areas represented in proportion to its share of the bank: Administration and Compliance; Building Envelope; Mechanical and Water Heating; Lighting and Electrical Power; Performance, Commissioning and Existing Buildings. Question order and answer order are shuffled every time you sit it.
This is GCHS practice, not an official test. It checks what you have retained from the lessons, based on the 2021 IECC commercial provisions. Treat it as open book if you like: in the field you will have the adopted code and its local amendments in hand, and knowing where to look matters as much as memorized numbers.
