The course was super helpful for narrowing my study to only the topics that mattered. As always, practice exams are very important - maybe even more important that review material. They helped me gauge my weaknesses and focus my study. The Bowen practice questions were similar in content, difficulty, and style to the real thing. Needless to say, I passed!

I passed [the CIH exam] and I wanted to say thanks so much for everything Russ. Your course was an amazing investment, and it really helped me understand what I needed to know. This is also my first online live course, and I was a little skeptical at first, and I think courses like this can only work when you have a dedicated instructor - which Russ is.  I also appreciate everyone in the forums posting all your questions and generating your discussions. Some of those materials really helped me a lot. This was a good experience for me.

A huge thank you to Russ for providing me with the fundamental resources in which to build upon in my preparation for the CIH exam. I had seen a post stating that someone felt that the Bowen CIH course only represented about 10% of their actual exam. I find this hard to believe as a recent successful candidate. Russ said himself, that the course is not the be all end all in preparing for the exam, however, it will get you pretty darn close, the rest is up to you. I promise you that is true if you fully comprehend the material that Russ has provided you with. My goal was to pass on the first try; therefore I put in around 1,200 hours of preparation for the exam dating back to February 2017. I truly appreciate his product. He has dedicated his career to advancing our profession and helping to create a better-rounded safety professional. Whether it is the CHMM, CSP or CIH, there are many professionals in our industry with credentials that can be tied back to Bowen EHS. If you effectively utilize all of the resources that he offers you will be very close to passing your exams, the last little bit to get over the threshold is still up to you.

I would like to say THANK YOU VERY MUCH to Russ, Nikki and the Bowen Staff for helping me and being patient with me when I was preparing for this very challenging exam. It was definitely a humbling experience. I wouldn’t have been able to do it without them and my very supportive, smart, funny and patient study buddies. For those who are going to be taking this exam...I cannot stress enough how instrumental the Bowen material (lectures, study session, practice quizzes, posted material, etc.) was to my success in passing this exam. Follow everything Russ says...from what to read and what flashcards to make, how frequent to study, to resting before the test. For the actual test, I skipped all the math and did them at the end. It’s very effective. Thank you again for this experience.

I joined the happy alumni who have now achieved the Preliminary Pass result on my exam. It was a good feeling. This time around, I knew it. I wasn't even nervous as I waited for the final result when I clicked the button (OK maybe just a tiny bit). I thank Russ and the entire Bowen team for standing behind me, helping me study and study some more, encouraging me, and everyone in the study groups for each exam. I couldn't have done it without all of your support, I'm sure. Part of me feels like I should have passed a year ago, right after I took this Bowen prep course. I missed passing by 1.2%, probably 2 questions. Disappointing, but I studied hard again for the spring exam. That one I missed by 0.6%, probably 1 question. That one was hard to take. But I'm resilient, so I picked myself up and tried again. Good luck to all of you, and a sincere thank-you to Russ and all of the Bowen team.

I took you prep class this fall (well the one that started in July) and received a preliminary pass after the exam. I wanted to thank you and your staff for all the help and guidance. It wouldn’t have been possible without you all.

Got my letter saying that I passed the CIH exam! Thanks for the help Russ and everybody! Good luck to those who still need to take the test! Radiation and Thermal Stressors/ Ergonomics gave me the most trouble.

Hi Russ, Just wanted to let you know that I PASSED my CIH test! Woo! Hoo! I took your class last fall and almost passed. I took the class again this year. I only studied your material and made sure I could score at least an 80 on each practice test over and over and over. I probably studied/practiced/reviewed everything at least 15-20 hours per week for 2.5 months. I also worked the previous practice questions you supply us as well in the additional resources section. My perception of the test was that there were not as many problems requiring the use of the formula sheets, however, when there were, I could work those problems. There were a lot of questions you had to think about the answer, but I believe the information you provided in the online class covered most of it. I am very happy that I passed! Thank you so much for your class and teaching!

Preliminary pass - CIH exam! I used Russ' recommended approach of skipping all the math or really wordy questions the first time through. This was really helpful for me. I spent too much time studying the complicated calculations. There were not as many calculations as I expected and a lot of tox. Good luck everyone! And thanks for a great course Russ!

I took the CIH exam and got preliminary pass!!! Thanks to the Bowen EHS team especially Russ & Rick, I listened to Russ lectures multiple times to learn and clear many difficult concepts. I prepared my flashcards especially Toxicology and spent some time with IH reference & study guide, Very good book nicely written in short to cover all rubrics of IH. I also spent a lot of time to practice calculations especially ventilation, noise, general science equations etc. If you want to make your score higher just practice more and more calculations problems. This will definitely help to pass the exam. Lastly, Bowen practice questions were really good preparation for the exam Good luck to all those taking the exam.
