“I enjoyed the Ob/Gyn CD-ROM Mock Exam, and I passed! The content was on the test. I loved the Ultrasound Physics CD, too. I know both CDs helped me to obtain my RDMS in obgyn.”—Stephani Rockwood, RDMS

“The Ultrasound Physics CD-ROM Mock Exam was the best learning tool I used in preparation for the registry exam. It was easy to use. The material was easy to understand. I passed.”—Christina Bratton-Finkbeiner, RTR, RDMS

“I studied relentlessly with your physics CD. I finished with the ARDMS SPI exam in less than an hour. It was a piece of cake. Y’all had it right on.”—Jesica Works-Cassell, RDMS

"I passed the UPI exam! I needed hardcore questions that were close to the exam—and that's what this CD delivered. I nailed it!"—Wendy Okray, RDMS

"I love your mock exams. They are full of questions that make me apply my knowledge in different situations and circumstances. I have a lot of other books with questions, but the Davies mock exams are much better. And I learned a serious lesson when I took my physics exam and failed by only 3 points: It's not enough to study only the textbooks. You have to be able to apply your facts, not just know them. That's what your mock exams give me."—Jeri Moser

"Edelman's questions were very simple—too simple. Davies provided me with more complex, challenging questions. I passed physics the second time around after studying with the Davies Ultrasound Physics CD-ROM Mock Exam."—Greta Warner, RDMS

"I passed! I went over the questions so many times, using both the book and CD, that as soon as I saw a real exam question I knew the answer."—Leonor Campos, RDMS

"These CDs are awesome because they show me which exam topics I'm prepared for and which I need to work on, automatically. And then I can use them to study those topics. I've used all of the products out there, and Davies is the only one who connects the dots. Anyone who doesn't use these is crazy."—Laurie Hokanson, RVT

“What made me pass the ARDMS physics exam was the Davies CD. I finished taking the exam in only 1 hour 8 minutes and passed. Your Ob/Gyn CD was so close to the exam, I finished it in just over an hour as well. Now I’m ready to study for the vascular exam and I’m using your CD. They are the best!.” —Lisa Tornabene, RDMS

“Your review products were excellent resources years ago when I passed the boards, and I recommend them highly to all students and former graduates. Many of my students have purchased the new Ultrasound Physics Review: SPI Edition and recommend it highly.” —Catherine Rominski, RT(R), RDMS, RVT

"I would like to thank Davies for developing a CD study tool for physics. It was a useful product for me, and I have to say that getting a 95 average on my exam was a celebrated moment."—William Guzman, RDMS

"The questions in this mock exam are all basically the same as those on the registry exam, just worded differently. It's great! I passed Ultrasound Physics and now I'm studying for Vascular Technology."—Rosenie Ridore, RDMS, RVT

"Since purchasing the Vascular Technology CD-ROM for me, and the Ultrasound Physics CD-ROM for my wife, we have both passed our respective exams! I am now an RDMS and an RVT. My wife Karin is now an RDCS. With the help of your study materials, we both passed the first time! If I ever need to take another exam in the future, I will make it a point to call on you folks again. Thanks for everything!"—Dale R. Roach, RDMS, RVT

"I was so afraid of this test. I heard it was brutal. I came to your office and explained that I am the backbone of my family and HAD to pass. Everything depended on it--my job and my family. You were kind enough to talk to me and give me your advice. I used your Ultrasound Physics CD-ROM Mock Exam and I kicked ***. I stand by your product. It showed me exactly which topics I was strong and weak in and explained the concepts clearly. I focused on my weaknesses and passed. I hardly missed any questions. Now I am coming to get the Abdominal Sonography CD-ROM Mock Exam. I am a believer in your products because they deliver what they promise."—Miguel de Paz
