Purpose of this Course
•This course is a Review Course for the Boilers and Steam Systems section of the CEM test. It provides a detailed and in depth review of the material presented at the Five Day CEM Training Course, as well as providing supplementary materials and information that the CEM Instructors do not usually have the time to cover in the Five Day course.
•This course also provides:
–Practice problems and examples to improve your understanding of Boilers and Steam Systems; and to increase your problem solving skills.
–A 20 question Practice Test to better prepare you for the Boilers and Steam Systems section of the CEM test.
