In the EHS profession, the CSP and CIH certifications are prestigious international credentials that significantly boost a practitioner's competitiveness and career potential. However, preparing for these exams is challenging; many candidates struggle to identify key exam topics or maintain a structured study pace, resulting in wasted time and resources.
This session features Ray Luo, a student from the Birui online program, who passed the CIH exam in November 2025 and the CSP exam in June 2026. He will provide a comprehensive review of both exams and break down the lessons learned from his own missteps, helping current candidates avoid common pitfalls and drastically shorten the trial-and-error phase of their preparation.
If you are preparing for the CSP or CIH exams but are struggling with low study efficiency or a lack of clear direction—and are looking for a systematic course and a personalized study plan—please contact "Birui" (our team) to sign up for this sharing session.
