<p>I do believe that the 80-20 rule does apply esp in the&nbsp;educational setting. I am an RN and practiced in a hospital setting for 25 years. Although I had to go to college to get my nursing degree in order to pass boards the majority of what I learned in the feild of nursing was on the job training and gaining experience over the years. I am currently a nursing instructor and tell all of my students that although this period of their nursing education is at best overwhelming do to the mass quanity of information they are learning that most of the reinforced&nbsp;learning will come from on the job experience of working as a nurse.</p>
