We wrote this workbook for the Maryland Stationary Engineer Grade 3 license examination — the grade that oversees boilers of 100 to 299 horsepower in any building. Its twelve chapters follow PSI's published Grade 3 content outline, 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.
