We wrote this workbook for the Maryland Stationary Engineer Grade 5 and Grade 4 license examinations — the entry grades of Maryland's stationary engineer ladder, covering boilers of 30 to 99 horsepower. Its ten chapters follow PSI's published content outline for Grades 5 & 4, area by area at the outline's own weights, and every practice question comes with a worked explanation and a source line, so you can see why the answer is right and where it came from.
