Richard: August 2020

"Passed my ASP this morning! Datachem was all I used to study. Thanks!!"


Matt: October 2018

"I used DataChem Software to help me prepare for the ASP and I certified last April. I believe the software was critical to my success."

Brian: September 2018

"I'm happy to report I passed the ASP on my first attempt with the assistance of DataChem Software again!"

Duane: April 2018

"I used the DATACHEM ASP online software to pass the ASP exam.  I really liked it.  I am in the process of purchasing the CSP online software."

Jon: October 2017

​"I passed the ASP Exam on Monday.  Your product was very helpful. Your questions were similar to those on the ASP Exam compared to other exam preparation products I have used in the past.  Keep up the good work."

Cardinal: 2017

"I passed the ASP exam. Thanks."

Carolyn: July 2016

"Out of all the study aids I used for the ASP, DataChem was the best."

I want to write a review of your program. I bought a 30 day program and went through it as best as i could with the limited time i had. The program really focused on the topics that are essential, and even though i wished i had more time to use the Data Chem program, i was very satisfied. I have purchased several books, flash cards etc, but Data chem really was the best of them all. I passed on my first attempt with theDatachem ccm program being the last body of work i used. Thank you


Toni, December 2021

Thank you. I passed my exam. I used your software repetitively. It helped tremendously


Kim, September 2021

I passed the CCM today!  Thanks for providing this great, useful study and exam guide!


Sherry, March 2021

I passed my Certified Case Management exam! I primarily used DataChem to prepare for this exam. A recipe for success is to follow the DataChem instructions, practice the questions and complete the practice tests! 


Michele, August 2020

I initially took a practice test with 180 random question to see where I was weakest. I then did all the study questions in those areas. Finally, I continued doing practice tests and reviewed the wrong answers. The question were much more complex than on the exam itself but they taught me to really read the questions carefully. They also taught me where to dig deeper and study more. Great resource! THANKS so much for making it. Some of us need to take practice test to learn and build confidence. When I started seeing 70’s and higher I felt I knew the subject. Worth every penny to me!


SW:    April 2020

Datachem was critical in my passing.   I have to admit I failed the first time and then I heard about Datachem.


Leslie:  January 2020

First I want to thank Hugh and Marie for their assistance and encouragement, you both are an asset to Data Chem!  This tutorial was worth  every penny. I took the exam on Saturday and I am sure I would have never passed without having studied with the assistance presented with the Data Chem process. You have to put the work in but the way this is structured helps you to study all the right things.


Paula: December 2019

I am full of joy as I passed the CCM exam. I am so Happy that DataChemSoftware was available to me. I don't think I would have passed without having these questions available.  I am so appreciative of your service.


Carolyn:  September 2019

I passed the CCM exam 8/30/19! The test bank questions prepared me very well for the CCM examination! 


Sherri:  August 2019

Good morning I just wanted to offer feed back on the Data Chem Software for the CCM exam. This is the second time I have used this product. I had passed the exam before and unfortunately let the certification expire resulting in having to re take the exam. (painful) Both times, I found the system extremely easy to use and the options of how, when, where to begin testing plus the options for review were excellent. I found the content in questioning of each domain relevant and enlightening. The method in which the questions are asked definitely prepared me for the exam even though there are no T/F or "exception" questions on the actual CCM exam, I found it beneficial to have them on the DataChem product to "prepare the mind" so to speak. The actual CCM exam was far easier than the DataChem questions I felt (or maybe the complexity of DataChem had me feeling that way) and did not go as deep as they could have with the content. They did make sure the important concepts and theory behind the questions were related to a CM's understanding. Having said that, the exam was constructed fairly and was indeed relevant. I wanted you to know I LOVE the DATACHEM software for preparation in testing for the exams. I had purchased more time than needed...Just in case...I failed and needed to continue studying. I have time left over for sale. lol Thank you for a great product. It for sure played a huge part in my passing the CCM exam.


B. Anderson: May 2018

"I used the DataChem software and passed the test on 4/30/18.  Absolutely loved your program.  I attribute my success to your program."

KG: April 2018

"Thank you so much - I passed the CCM exam!!! DataChem definitely helped me for sure!"

Priscilla: April 2018

"I took the National Case Management exam and I passed!!! with much help from the DataChem online test questions.  That is the second time I have used DataChem.. in 2005 I got the CRRN CD and I passed that as well.
Thank you so much.  I always recommend DataChem!!"

Joni: April 2018

"Just took my CCM test on 4/21/18 and passed! Your questions with the rationale answers not only helped but it allowed me to re-read each question and critically figure out what it was asking and then narrow out the best answers to that question and then by reviewing the rationale answer, I was able to see what I needed to improve on. Several questions or very close to its content were on my exam and helped me to feel much more comfortable. My only regret is that I started your software three weeks ago and not sooner (I kept putting it off). I have to tell you that I crammed as much info as I could in those three weeks and it worked! Thank you so much!! Best money I could have spent! It's not only knowing the correct answers to the question but truly understanding what is being asked and then narrow down to the best possible answer, this software helped!"

"I just passed my CCM. Thanks!!!

Oh-and my compliments on all the updates to the program (as far as having downloads and online access available). When I ordered it back in 2013, it was still running off cd, which was pretty clunky-but the content was spectacular. I HAMMERED part one of the CHP exam, and have recommended your program to many people. I just ordered the updated version to assist me in studying for part two, as it has been six years since I took part one.

I just wanted to say thank you for your software. In searching for study materials to use for my CHST prep, many colleagues said to use DataChem. So I did. I will not mince words: Your program kicked my butt and was very challenging! But when I sat down yesterday for my CHST examination, it was like looking at your program...different but very familiar. Needless to say, but your program gave me the confidence I needed and reinforced my knowledge for yesterday's test. I am proud to say that I certified for my CHST yesterday, and I owe a huge portion of it to your program. I am now working on OHST certification and, of course, DataChem is a welcome part of the process. Thank you for your product!

AB: November 2018

"Just wanted to follow-up with you and to let you know that DataChem has been a tremendous help in my preparation to the CHST exam!"

Jonathan: May 2018

"I purchased DataChem only three days before my CHST exam.  I completed all 971 questions.  I did the ones I missed twice.  I Passed!!! Thank you for a great product!"

Raghu: February 2018

"I just got a chance to write my feedback about my CHST examination.  I scheduled my exam on 3rd Jan, 2018. I purchased the DataChem CHST exam on 26th Dec, 2017 and guess what.  One week of preparation (full time) I passed the CHST exam on one sit, 3rd Jan, 2018.  It was one of the best exam preparation methods that I found. DataChem was absolutely the best course I've had in a long time. It was structured perfectly; all the CHST course topics were covered perfectly with explanations."

Sidney: August 2017

"​I had purchased your system and passed my CHST on the first try."

Abdul, June 2021

I am happy to inform you that I have passed CIH exam in my first attempt. Thank you Datachem team for your support. Datachem material was useful and helped us to a good extent.


Boko, July 2020

I have finally passed my CIH exam on June 27, 2020. Datachem CIH prep V.10 software was a great asset for my study.
Thank you and your team for your great help....  Again, Datachem software CIH Exam Prep V.10 is a great tool for a Certified Industrial Hygienist. I will recommend this software for anyone who wants to write the CIH Exam.


Jerry:  January 2020

I first used the DATACHEM software and it helped me pass the CIH exam twenty years ago.  I used it again recently to challenge the test again, and it was updated, well-written, and gave me a good background in a number of IH-related problems that were new to me.  Much to my amazement I passed this time too!  I highly recommend it to any interested-professional.  The software design was easy to use and just great


Evan:  August 2019

Datachem is much more than a bank of questions! What I found most helpful was the practice test format.  I used that to identify my areas of weakness and spent all of my effort on those topics instead of working through tons of material that I was already proficient in.  


JG: June 2018

"The CIH program was the best of all the study materials I used."


Denis: May 2018

"I passed the CIH exam on Friday.  I bought three study aids and DataChem was the best by far."


JW: April 2018

"I am writing to let you know that I thoroughly enjoy your CIHprep software I purchased a month ago.  Because of the experience I am thinking about getting a CSPprep too."


Bruce: March 2018

"I passed, thanks, talk with you in 4 years."


Jeff: November 2017

"I passed the CIH.  The software was great!"


Robert: October 2017

"I thought highly of this training tool.  Passed the CIH exam this morning."

Robert: September 2017

"The CIHprep software has proven to be one of the greatest investments in my career.  It provided an important structure to focus my exam preparations, it helped me identify specific areas where I needed additional knowledge, and it provided a strategy for passing the CIH exam on my first attempt.

Investing in your CIH exam should begin with the use of CIHprep.

Thanks again for the great product.  I advise students to start with DataChem. It's a great way to assess where you are and what additional studying is needed."

Vikrum: June 2017

"DataChem Software was my primary means of preparation.  Going into the exam, I thought I knew a fair bit about IH and considered myself a technically sound practitioner of the field.

Taking the initial assessment on DataChem showed me....otherwise.  I would estimate that DataChem problems (specifically the calculation portions) were at least two to three times harder than what appeared on the exam. Hammering those questions for three hours a day over a two and a half month period allowed me to breeze through the exam.

Anyways, I can't say enough good things about your software as it is a truly great product."

Occupational Hygiene and Safety Technician

Bill:  October 2019

Your OHSTprep program is grueling, demanding, tough, challenging, and punishing…and those are the nice adjectives!  Because of this, it more than prepared me for the test.  As a matter of fact, I had to reread many of the test questions to make sure it was as easy as I thought it was, because the OSHT prep was that challenging.  Many may not appreciate it like I do, but they will when they take the exam.

If you are a safety professional studying for the OSHT, YOU OWE IT TO YOURSELF TO USE THIS MATERIAL!!!  THANK YOU DataChem for your product!!! 

Brooke: July 2016

"I used the OHST study guide and it helped me achieve my OHST. Thank you and keep up the great work."
