Registered fire engineer takes three exams, and the validity of the three exams is kept for three years, which means that he can pass the three exams within three years. These three subjects are fire safety technology practice, fire safety case analysis and comprehensive ability of fire safety technology.

The examination questions of "Fire Safety Technology Practice" and "Comprehensive Ability of Fire Technology" are objective questions. "Multiple-choice question" requires that one of the options best meets the meaning of the question as the answer. "Multiple-choice questions" have two or more options for each question, and the wrong choice does not score; Omitted, 0.5 points will be deducted for each question. Among all multiple-choice questions, there are 80 single-choice questions, each with 1 point; 20 multiple-choice questions, 2 points for each question.

The fire safety case analysis (15) has six subjective questions, and the subjective questions are comprehensive case analysis questions. After 20 16, the questions are 2 multiple-choice questions +4 subjective questions, and the subjective questions are comprehensive case analysis questions. The total scores of the three subjects were 120. Each subject needs to reach more than 72 points (including 72 points).
