CIH Pass! First time taking the exam and first time using a course for preparation. I think the structure helped focus my supplemental reading. Carried the TLV book with me when I didn't use Quizlet. Thanks Bowen!

I sat for the CIH exam yesterday and received the P+ I worked for!!!! Just wanted to say THANKS to the crew at Bowen EHS and all the studying sessions, etc. This was my second attempt after missing the mark last fall. Bowen allowed me to sit through another round of classes and it paid off. Best regards and good luck to those who are sitting next week!

I will feel better when I receive the official letter from ABIH! I have the "preliminary" pass! I am still in shock after seeing that, and am really, really tired right now. Thank you, everyone, for your support during classes and great feedback to questions! Also, a big "thank you" to Mr. Russ Bowen for everything! Your teaching methods really helped me pass this exam, especially since it is over 20 years since I graduated from college!

Sat for the CIH exam and got the green checkmark - Preliminary Pass! Phew! Thanks for all of the help, education and fun provided by Bowen EHS staff. I feel certain I would not have been successful without completing this preparation material.

I took the CIH exam today and received a preliminary pass. I had to stare at the screen for a second to realize I had passed..the big green circle with pass in it was not getting through. I would like to thank Russ and the rest of my classmates for their help because without them I would not have been able to pass. The workshop was awesome and got me pointed in the right direction on where to focus my energy. Thanks.

Passed the CIH exam! First, I want to thank Rick for a wonderful class last fall in NC. In addition to taking the class in person, I also listened to the recordings over and over. At the gym, in the car, etc. When in doubt, listen to lectures. There were many, many questions where I had Rick's voice from the lectures playing in my head, telling me the answer because I practically remembered the lectures. The exam was tough! I thought I over prepared but was surprised how hard some questions were. Overall, the math was really easy. Bowen's math problems are very good prep for this test. However, there are not many math problems. The hard part were the wordy questions. I won't get into details but there were a handful of questions where they would say, "when doing or developing X, what would you do first, or which is the most important factor." Which are tough because you have to really think what is the best answer, and all 4 answers sound like they are important. The other tricky part was semi-detailed questions on the most random aspects of IH. Very hard to prepare for those. Most of those were either judgment calls or I just happened to have experience. Honestly, I thought a handful of questions were unfair... but those could have been the experimental ones for all I know. My best advice is to try not to remember facts as much as understand the concepts of what each rubric is all about. The Bowen course is a fantastic baseline. Use it as a guide and expand on the subjects it covers. The Fleeger guide helps some, the TLV booklet is crucial! Read it! and the Burgess book is also really good. If you can't get a copy, just Wikipedia search the industries and watch youtube videos. There is a lot of good content.

I took the CIH exam today and received a Preliminary Pass!! This was my second attempt at conquering the beast and the hard work paid off. The lectures by the Bowen team provided a great foundation as to what to expect on the exam. For my second attempt, I also read Recognition of Health Hazards in Industry (by William Burgess) and Industrial Hygiene Reference and Study Guide (by Allan Fleeger and Dean Linquist). I would recommend these books and also recommend to take notes/make flashcards as needed. DataChem was also very helpful as it pointed out my weak spots that I needed to focus on. Good luck to everyone sitting! If it doesn't go your way just remember how far you have come and how much you have learned thus far. You can do it!

Preliminary Pass!! Here is my advice from this whole process: Bowen's class is awesome. It prepares you very well for the CIH exam, especially the math! But you can't rely on it solely to get you to pass. Bowen's material will get you darn close to the passing score but to guarantee a pass you will need to read up on other materials. Studying 24/7 like a lunatic and not having a life does not help. It actually makes you doubt your answers on the exam or makes you misread the questions causing you to fail (at least for me it did). On my second time around, I made sure I had a life. I only studied about an hour a day during the weekday and if I got a chance during the weekend. Remember life still goes on even while studying for the CIH! Lastly stay with it, even if you fail. Keep on taking the exam until you pass. You will be surprised at how much you learn from each attempt. Best of luck to you all!

I took the CIH exam earlier this week and received a preliminary pass!! WHAT A RELIEF! I can say with confidence that the Bowen course is a great prep tool! I have already recommended it to two other colleagues who are preparing for the exam. I will probably be back for the CSP prep too. In addition to obviously completing the course, I highly recommend downloading the app to your phone so that you can take the 10 question test on the go. I also suggest creating flash cards on quizlet (or wherever) and downloading that app to your phone. This was very valuable. I created over 400 flashcards and looked at them daily. I also did a ton of the mini-exams on the premium resources. I reached the point that I even scored a 100% once. I would go back and look at all of the solutions, even the ones I got correct, to make sure that I completely understood the rationale and any additional material that I should know. I can't express how excited I am to have my life back! As you may gather from my recommendations, I spent A LOT OF TIME studying! Best of luck to you all! And that feeling when looking at the screen telling me that I passed, was so worth it all! And that fact that I don't have to do it again :)

I am proud to announce that I have passed the Spring 2017 version of the CIH exam. This was my second attempt. I kept studying and didn't get discouraged when I failed it the first time I attempted it. Now - back to my normal life. It's so strange not having my head in a book every waking moment. Good luck to those taking the exam this Spring!
