Most professionals preparing to take the CIH, CSP or ASP exam have heard of Datachem and their exam preparation software. The company has been around for many years and they have a good reputation. Still with a price of $299 for the ASP software and $399 for the CSP and CIH programs, many individuals wonder if it is cost. (There is also an ASP/CSP combo program available for $598).
I can personally attest to the value of the Datachem software because I used it while preparing for my own exams. The DataChem programs are easy to use and contains thousands of questions that are very similar to what you will see on the actual exam. You can take full practice tests or just review specific categories. The program also allows users to mark questions for further study and provides answers with detailed explanations to each question. The Datachem software is a great product and definitely worth the costs. Another great feature of the software is that you can print off questions from the practice tests for study.
During my own exam preparation, I liked to take a practice test and then go back and review the answers and explanations for any questions I missed. I would then print off all of these questions and explanations and review throughout my week. The software will pull these questions out for you fairly easily; however, I found the easiest way to print them was to copy and paste each question I wanted to review into one word document. I would then print and save a copy of the document for review. This is a great way to focus on your weaknesses and not spend too much time on the areas you have already mastered.
Datachem provides enough questions that you will never reach a point that you have the questions memorized or run out of material. In addition to great study material, the practice tests help you get used to sitting at a computer and answering questions for long periods of time; this is an important part of prepping for exam day. I fully recommend using the DataChem software in your preparations for the exam.
If your resources are limited and you are trying to cut on costs, I would forgo a prep course that can require expensive travel and focus your studies solely on the DataChem software. It will provide you the greatest overall value. There are a lot of ways to best utilize the software and go about studying for the exam. You just need to find what will work for you.
