The difficulty of the Registered Safety Engineer exam can be analyzed from various aspects. The exam covers multiple subjects and has increased in difficulty since the 2019 reforms. With seven specialization directions, the exam requires a thorough understanding of safety regulations and practices. While the exam for Intermediate Safety Engineers involves four subjects, with 'Safety Production Technical Foundation' being relatively easier, success depends on the candidate's preparation and dedication. The score of Intermediate Safety Engineer is valid for four years, allowing candidates ample time to pass all four subjects. However, the historical pass rate has been around 13%-15%, indicating the need for serious preparation. Success in the exam ultimately depends on the candidate's attitude towards studying and the effort put into revising the necessary knowledge points. By dedicating time and energy to studying, candidates can increase their chances of passing the exam within a shorter timeframe.
