I have really enjoyed working through this vast resource and even learned some things today! The links are easy to use, the graphics are colorful and crips, the explanations clear. The activities are varied and address several methods of learning. Feedback is provided during multiple choice answers to facilitate learning if a correct or wrong choice is made (RSI). Fabulous! I will spend more time on this site.
Not all links provide information. Most disappointing was the interpretation link when working in some of the app features, for example calculating body mass index. This seemed to be consistent on several pages. There are a few other links that when clicked on did not add content.
