Testimonials

I love RDstudy.com - Thank You!


I love RDstudy.com. I never write reviews, but I had to this time. Studying alone for the RD exam was so taxing for me I postponed it for 3 years, crazy, I know. I found RDstudy.com and got the support I needed. The customer service is awesome. The Ask the RD! feature is so helpful for calculations and they responded in a timely manner. I asked customer service, why is this service not more well known, I was told they are improving their network to support more users and are planning to expand. I am so happy that this service is available for those like myself who felt so overwhelmed by independent study. RDstudy.com is the way to go!

RDSTUDY - ESSENTIAL TO SUCCESS!


To Rob and the RDstudy Team,

I passed the RD exam thanks to the OUTSTANDING services of RDstudy. Other study materials – focusing on content – cannot match the combination of tests, videos and staff support that RD study provides. I loved how I could customize the services, focusing on tests, videos or Ask the RD questions, depending where I was at in my study process. I also learned from RD study how to become a more successful *test-taker.* That is, I vastly improved in analyzing and correctly interpreting test questions. Information alone is definitely NOT enough to pass the RD exam.

The number one reason to subscribe to RDstudy is the Ask the RD feature. The staff promptly, thoroughly and clearly answers questions on any exam topic. I was truly amazed by the depth, creativity and clinical detail in many of the replies I received. This interactive feature was a major key to my success for it made the study process more effective and immensely enjoyable.

Forever grateful!

God bless,

New RD, PhD, CA

I am an RD!


After taking the RD exam for the third time and reading the report that stated, "Sorry you have Failed", I was devastated . I did not know what to do. I knew I understood the material , but I could not figure out what I was doing wrong. Nevertheless, I decided I would keep trying. This is what I went to school for. This is what I invested so much time, money, sweat, and tears into. I knew I was destined to be an RD. I had to find another route or a different way to study. I had already invested money in a study program, but I needed something different. After using RDstudy.com, I realized immediately what I was doing wrong. I knew my material, but I had to learn how to take the test. RDstudy.com prepared me to focus more on what the questions were asking rather than distracting details. There were hundreds of sample questions with thorough explanations but, the video tutorials were my favorite! The videos helped solidify key exam concepts. Nonetheless, I took the RD exam for the fourth time, and I was so excited to read a different report that stated, "Congratulations You Passed"! I know RDstudy.com was a big contributor to my success. I am so grateful for the program and the staff. I am excited and elated to finally be able to able to say I am an RD! For lasting words of encouragement I would like to say do not give up, keep the faith, stay in the race and give RDstudy.com a try!

I Passed! Thank You!!

Hi Rob! I just wanted to share some good news with you. I passed my exam today!!! I got a 28 and the test only went up to 125 questions. I want to thank you for all your help!! I definitely utilized all your exam tips and changed the way I studied. I didn't rely so much on the other study guides this time around (except for some supplemental material), but I did utilize more outside reading materials (ADA position papers, management/food service books) and my scores on the RDstudy program improved a lot before I took the final exam. Again THANK YOU THANK YOU THANK YOU!!!!!!!

New RD, CA


Another Passed on First Try!

Entire Internship Class Passed on First Attempt!

I believe that RDstudy.com was definitely the key to passing the RD exam. I passed on my first time in the score range of the 30s! RDstudy.com helped me understand how to pick the best answers and they were always around if I had questions. I completed the Ingall's Memorial Dietetic Internship and my entire class passed on the first time with the help of RDstudy.com. Our Program Director included it as part of our program requirements and it was completely worth it!

Thank you, thank you, thank you to the RDstudy.com Staff.

Great News!

I just wanted you to know the absolute greatest news!!!! I just PASSED MY RD EXAM today!!!

I had taken the test several times before, and really struggled with all of the abundant amount of information out there - I tried some of the most recommended resources. But I have to say after a year of studying many companies' resources, RDstudy.com offers the best and comprehensive review that I have ever work with.

The simulated tests helped prepare for the real test conditions, and the rationales gave me a basis to re-check my work. The email responses to difficult questions were quick and thorough and became the turning point in the way I was to analyze the answers and eventually pass the test. This resource will be recommended to every dietetic student I know because it really helps prepare one for the exam! Thank you!

Finally Successful!

I finally passed the RD exam on Friday!!

It took me until the 4th try and I am so glad that I found RDstudy.com. It helped me out so much!

New RD, North Carolina


Passed on First Attempt!

I really wanted to thank you for creating RDstudy.com. I passed on my first try!!

I had purchased two other study programs and did not feel like I was getting what I needed out of them. Your program with explanations at the end of each question and the Power Point study modules really helped me to focus on any of my weak points and review those I felt I already had a handle on. The calculations were also very helpful, as it gave me confidence that I understood the questions. It did take time to go through your program, but on top of passing my RD exam, I feel better prepared to start my new career. Thanks again for helping me accomplish my goal.

New RD, California


Another Successful Candidate!

New RD, Washington


New Job Awaits!

I just had to write to say thank you as I successfully passed my RD exam!

I really do owe it to you! Coming from Canada I had NO idea what to expect for this exam as our exam is very different. I had purchased another company's study guide but after weeks of reading it over and over I wasn't retaining the information.

The videos were just what I needed as I am a very visual learner and they were taught in such a way that made sense and used a lot of examples. Also the practice questions were the most beneficial; I must have done all of them in the end. Your questions were much harder than the real exam but that is why I passed!

As I had accepted a position in Los Angeles and my entire family was moving there in just 2 weeks I had major pressure to pass. Thank you again so much, I owe my future career and life in the U.S. to your help!

New RD, California

Best Study Tool!

I think RDStudy.com was the most beneficial study tool I used to study for the exam. I just passed on the first try!!

The video tutorials were very thorough, as were the explanations for the correct answers on the practice exams. I feel like I truly learned the material and was able to apply my understanding of concepts to the actual RD exam.

I think this is far more useful than just memorizing answers from exams, which is what some other exam prep companies seem to encourage.

Thanks again for creating a great and effective learning tool, and for the excellent customer service!

New RD, Georgia


Stayed Focused!

Yay!!!!!! I took the exam yesterday afternoon and passed.

Honestly, I couldn't have done it without you. You gave me the proper directions and great tips as needed which helped me stay on track. What a great relief!

Rob, thanks a million and my thanks to everyone else on the team. Keep up the good work!

Most Helpful Study Tool!

I retook the RD exam today and passed thanks to you!!

I have invested a lot of money in other test-prep programs, but I felt RDstudy.com's computerized practice exams helped me the best and was most like the actual exam. The most important thing I valued from purchasing your program was the support I received via emails. I appreciate the time you took to answer my questions. I felt like I really had a study buddy.

I will definitely be telling ALL graduating students about your program. Thank you so much!!!!!!!
