The Science Behind Mobile Learning:
Overloading your brain with too much information at once is a common study mistake. Research has shown that smaller, more frequent study sessions are the key to knowledge retention. In other words, taking short quizzes on the go is a much more effective means of exam preparation than reading page after page in a textbook. Apps offer the benefit of interaction, which means you’re far more likely to remember a concept you engage with rather than one you’ve only read about.

Take your dietitian studies with you, no matter where life takes you.

So helpful!

It is well worth it to purchase the full version of this app! I used this in combination with Inman and passed on the first time! Having the question explanations helped me actually learn the concept rather than just the answer to the question. I also liked how it gave you a score on the domains to help you identify where you need to study more. The quick 10 minute quizzes were awesome! So user friendly, I couldn’t recommend this app more!

A good time filler and decent questions

Most of These questions are not as hard as the harder questions in visual veggies but definitely as hard as the easier ones. But it is all very good information and definitely possible questions I think I might see on the RD exam. There is a good variety of information and I’m beginning to lean some of the managerial concepts like Maslows Hierarchy and similar theories. I love that it includes the explanation for why a question is right or wrong. This is a great study feature and helps cement the information. I read them every time even if I knew the answer because it explains the incorrect answers as well. I’ve also started memorizing some of the harder managerial food service questions like BEP, break even point. I wish there were more questions on things like what different labs indicate and more on medications. Also so far I’ve only gotten one question on mEq conversions for calcium. I’ve actually learned this one. If the others were included I’d be able to learn those as well. But I’d say it’s worth the $24. I also like that questions repeat. This is good for review and for learning ones I missed.

Almost perfect

This app is great and is worth every penny to upgrade and get access to more questions. It was so nice to be able to tailor my practice exams to the amount of time I had or the domain I was struggling in most. I especially appreciated the thorough explanations of not only the correct answers, but why the other choices don’t fit. The only thing that was frustrating was that it said it had 650 practice questions in the databank but every test I took I would get at least 25% repeat questions— as in identical, the answers weren’t even scrambled; So I found the performance metrics to be skewed since I was able to memorize answers without any higher thinking/conceptualization. All in all, I definitely recommend this and I passed my exam the first time!
