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.
