I’m Njoya Abdulaye a graduate from Green World Group Institute and I'm proud to say Green World Group Institute is the Best in the World to acquire any professional certificate with relentless sufficient understanding and application of the knowledge in real world life. Before getting my IGC, PSMS, etc I have been frustrated by many centers such that I almost gave up but when I came across Green World Group, I found professional tutors, with simplified and well-organized training materials, classes conducted in a well professional manner. I have won several awards and recommendations in my organization just because of Green World Group and their training methods helps me to understand the subject easily. Other centers who are only interested in your fees and their instructors appears in a rush and anxious, please beware and choose rightly your learning center, and I prefer Green World is the best HSE training organization in the world.
