I would like to thank the entire Bowen EHS staff for creating such a great online class. Because of them, I was successful in passing the (CIH) exam. Thanks again!

I just couldn't wait to take this test (CIH), so I booked it for the first day of the fall window and received a preliminary pass notification on the first attempt. I owe a significant debt to Russ Bowen for his course instruction and the wonderful resources this site offers. The course presented key topics and advised on great resources for more information, and the quizzes provided an easy means for measuring competency in each area. Thank you!

Taking the Bowen CIH review course was instrumental in helping me pass the CIH exam. Prior to taking this review course I was unsuccessful in passing the test as I found I did not study some of the material correctly. This course helps you to focus and strategize on how you study for the test which is extremely beneficial considering the extreme amount of material that you must learn and know.

Thanks Russ! Course [CIH] was great, but one really has to put the effort into this apart from just the course. I even got a 100% on Toxicology after getting 45% back in Spring 2014. All the best!

Have officially joined the ranks! Sat & passed. Seems 3rd time was the charm for this IH ( the first attempt was a terrible failure in fall 2013; spring 2014 was a successful failure in that I knew I needed to prepare more fully as I missed passing by 6 questions). Want to thank Bowen EHS for setting me up for success--but for those of you who were not successful this go-around, know that you still have to put in the work to fully benefit from what is provided in the Bowen course. Keep at it and don't be discouraged. And congrats to those who were successful!

Well, I took the CIH test last week and got a no pass. I felt really good going into it and actually didn't feel terrible while taking it so it was a bit of a surprise when I got the no pass. I went through all of the Bowen questions available, read the TLV book as well as others, went through all the lectures at least twice, took many "quizzes" and was getting 80-100% on them by the end. I even purchased the extra Bowen workbooks and went through all of them too. I am pretty disappointed and not quite sure how to study for the next time around. I guess I will just have to wait to get the letter telling me what rubrics to study harder in. I did enjoy this course and like I said, I thought I was pretty prepared for the test, but I guess there will be at least one more go around...

I pushed the submit button and closed my eyes. When I opened them, it said "are you sure you want to submit?", pushed the button, closed my launched into the survey. Then it launched into at least 2 more "are you sure you want to submit?". I thought I was going to have a heart attack but finally....finally I got the green check saying preliminary pass! (CIH exam) BOWEN is the best prep system EVER! I HIGHLY RECOMMEND!. Rick, you were a great instructor and host in Chapel Hill. Thank you!

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 felt very confident since the week previous, I had a feeling of being the Ready that I have not ever had in my life.I want to thank Bowen for the course and for the time that he answered my emails and phonecalls with questions, Also, I want to thank another premium member, whom I met thru the discussion board and he became my long-distance study buddy.
