About Chemical PE Exam Products

"My thanks to you for your excellent review books and website. I just got my notice that I passed the Principles & Practice for Chemical Engineering. There was no opportunity for Chem E review locally, and I relied on your manuals and review books and many of the comments from your posting pages. Just wanted to let you know that I could not have done it without your most helpful references." -- Doug Clark, PE

"I found your Chemical PE reference material to be very, very helpful, especially the Chemical Engineering Reference Manual. It was a great reference tool during the exam. Also, the practice exams were very helpful. When I reached a similar problem in the exam, I turned to where I had worked out the solutions to the practice exams, and plugged and chugged." -- Heather Heinrich, PE
