I like this study aid and the way it explains everything in detail. It is easy to read and understand. I like it a lot and I’m sure I will pass my test no problem since I have this material.

OHST Secrets Study Guide – Sonya



I have been very impressed with the study guide, it was very difficult for me to find a study guide that didn’t just have practice questions. This study guide gave me an opportunity to read terms, definitions and math problems prior to taking the practice exams.

OHST Secrets Study Guide – Brian



I personally think that both of these materials will be instrumental in ensuring that I succeed in pursuit of OHST certification. They make it easier for a family man who needs to prioritize his time in order to study. I have seen my knowledge grow over the past month.

OHST Secrets Study Guide – David



I recently purchased the OHST exam secrets study guide. Having worked (part-time) as our facility safety person for over 8 years, I felt confident I had the skills & knowledge to pass the OHST exam with little preparation. I was wrong! The study guide & online academy was very in-depth and identified areas of study I was deficient in. The OHST Exam secrets provided the detailed knowledge of all areas of testing without any of the “fluff”. The math section was especially helpful. It’s been a while since doing Algebra, Trig, Geometry & Statistics.

The only way you won’t do well is if you get the guide and don’t take advantage of what it has to offer.
