Client Feedback: CIH Exam Courses

We love getting honest feedback from our clients. In addition to letting us know how we are doing, they let us know what worked or didn't work for them while preparing for their CIH exam.

Read on to find out more.

We are serious about maintaining the integrity of the CIH exam and the certification process. Please help us by not posting any specific exam questions or exam content in your comments. If you do, we will have to modify or remove your feedback. Thank you for respecting this.

I received a different screen today than in the past "Preliminary Pass"!!! When I took the exam in the spring statistically I was within a couple of questions so that stung pretty good. I had attempted the exam on two previous attempts but hadn't really made good progress until attending the CIH review Russ and his team put together last spring. The value of studying for the CIH exam is honing on our craft; whether I passed the CIH or not, each time I attempted it the preparation provided a deeper and wider understanding that I was able to use in the profession.

Russ and Staff,  As others have said eloquently, I will say simply; thank you! A well-planned review course based on the pillars of learning is a remarkable example of a true mentor. You and your support staff are truly amazing and should be proud of the services provided to further careers of professionals around the world. Thank you for assisting and being a part in my journey. I received a preliminary pass Saturday on the CIH examination.

Finally got the message…congrats….preliminary results! Thank you for your encouragement through the years. I am a much stronger person because of this process. I’m encouraging my daughter to take your course!

I am happy and so relieved to report that I sat for the CIH exam today and received a preliminary pass! Such a huge relief! Thank you to everyone at Bowen but most especially Russ! You were a source of inspiration when I really thought I could not do it! I am recommending the course to everyone I know!!!

I completed my exam yesterday and am happy to report I received a preliminary pass on my first try; what a relief! I listened to the lectures at least twice, looked up information on workplace environments (YouTube videos are helpful), and I had tons of flashcards on every subject, but focused on toxicology, epidemiology, and ventilation. I also purchased the book Industrial-Occupational Hygiene Calculation: A Professional Reference by Stewart et al. Even though it has errors in the book, I found it to be extremely helpful in understanding the equations. I probably read through it 4 or 5 times. It really is a good idea to skip the math problems until the end. I was able to complete all the word problems, go back through the exam and complete the math problems, and run through all of them one more time in each 2.5-hour session. Thank you to Russ and the Bowen’s team.

Finished taking my CIH test today and received a preliminary pass! A lot of the comments I have been reading I found useful. What I will say is if you follow the rubric and study what your predecessors are telling you, may be a good idea and you should be fine. I put in between 2-3 hours a day for 8 weeks, and prior to that, I spent weekdays studying. Bowen quiz and practice questions have been invaluable to my progress. I also used the ACGIH IH calculations book, Quantitative IH book by Jack C ACGIH (great book, just doesn't present the questions in the same format as Bowen), did not use Datachem. If you understand how to manipulate the equations and have a good understanding of algebra I think you will do just fine on the math portion. At the end of the day, it's what we put into it that matter, you put the work in or you don't. Prepare like it's something you will only do once and you will be rewarded.  Thanks for everything Russ, I don't think I would have been as prepared as I would if not for your entire platform: class, study guides, quizzes, references, etc.

I just took the CIH exam and got a preliminary pass. Here is my take on it. I think the Bowen course is great and if you are very familiar and comfortable with it you would be fine. I had also studied with Datachem and I think it is not really useful because the questions are much more complicated than the test. I feel like the calculations are very simple in the test. If I had to study for it again I would concentrate on the TLV book, toxicology and the Bowen course.Good Luck to everyone taking it in November!

I took the CIH exam today and got that green checkmark! Thank you, Russ, for once again playing such a key role in my success! Thanks to you I've passed the ASP, CSP, and CIH all on the first pass. As others have done, I'll leave a few things for those who will be taking the exam soon...I spent about 4 months studying ~2 hours/day. I took the Bowen CIH mini (50 question) exam about 20 times during my 4 months and averaged low 80s. I took dozens of the 5-question exams in chem/basic science and radiation (my weak points). In retrospect, I wish I hadn't spent so much time studying the really difficult math problems since I found that the actual exam math problems were fairly straight-forward. I found the William Burgess book "Recognition of Health Hazards in Industry" to be extremely helpful. I didn't bother with the nitty-gritty within the book and only took out those golden nuggets that highlighted important information for the hygienist and seemed like good exam questions. I accompanied this book by watching YouTube videos on various processes like electroplating, iron and steel production, semiconductor production, degreasing, etc. I also used Quizlet CIH Tox cards that others have made. Good luck everyone! You can do this!

I just finished taking the CIH exam today, and boy was I relieved/excited/overwhelmed to see the big green circle indicating a preliminary pass, especially since this was my first time taking it. Thank you to the entire Bowen team, and more importantly, to all the users for their input in forums, past study sessions, etc. All of it was beneficial and instrumental to my success today. I wish everyone else all the best of luck.

I passed (the CIH exam)! Thank you so much for making this possible. This was my 2nd attempt overall, but the first attempt after taking your CIH Review Course. After failing the first time, I knew I needed more work on Toxicology and Ventilation. I found the TLV/BEI book and the ACGIH Ventilation Manual to be very helpful. I also watched a lot of YouTube videos to learn about different processes. The course also helped me strengthen my strengths. Thanks again!

It is indeed a tough test! I used DataChem CIH software religiously every day for almost a year, for at least 2 hours a day. Take practice tests. I printed out the Bowen CIH questions and put them onto flash cards. I played the Bowen CIH game 2 to 4x a day; strive for 100%. I purchased the AIHA "Industrial Hygiene Reference and Study Guide. Read this book every chance you get and memorize the content, as much as you can. Know this book and Ace the test!! I took the Bowen online CIH class and then immediately took the classroom CIH version. Difficult topics become more transparent in the classroom. Read the ACGIH TLV book; know the TLV's of common toxicants [benzene, lead, etc] but read [and re-read] the Definitions and Notations section!!!! Know your strengths and weaknesses. My strengths were chemistry, noise, bio-hazards, and PPE; my weaknesses were radiation and ventilation. Bowen will help with both of these topics. I passed ASP, CSP and CIH first time because I was extremely well prepared. I used Bowen for all three tests. It is the Boy Scout motto: Be Prepared!!!!!!!!!!

I passed! :) I cannot emphasize enough how valuable Bowen has been throughout the past few months (both the class and the premium resources). Although I took the CIH prep class in the summer of 2016, I didn’t actually start studying/preparing until January of this year and I can’t imagine how much more challenging it would have been without these resources to help keep me on track! Russ, thank you so much for putting together such a great course and study materials that made such a massive challenge be achievable and also for making me a better IH! Thanks also to Rick and Otto if they’re still out there! :)
