“I strongly recommend eatrightPREP® for future candidates preparing for the RD exam. I used eatrightPREP® as one of my primary resources and it was very helpful in preparing for the RD exam. The practice exams that simulate the actual exam format and evaluation of progress with each session helped me to identify areas that I needed to focus on to feel confident taking the RD exam. I passed the RD exam on my first try with a good score.”

“The eatrightPREP® practice questions and simulation exams helped me to feel more confident walking into the RD exam. The student forum made me feel like I wasn’t studying alone and the motivational messages that popped up as my scores improved or I completed various tasks kept me going. I have already recommended eatrightPREP® to other students preparing to take the RD exam and will continue to do so. I believe it contributed to my success in passing the exam.”
