Thank you for inquiring about my RD/DTR Study guide. Yes, it's completely free and you are welcome to pass the study guide along to help others succeed too. The goal of the study guide for me was not to make money but to simply help dietitians/diet techs who are in need of some good study material. All I ask in return is some feedback in order make the study guide better. Your welcome to post comments on youtube or you can e-mail me at [email protected] if you have any questions. Thanks.
