@mrnunez : I agree. If you take a class or a course and cannot apply that "knowledge" (using this term in a loose meaning) to solve a particular problem or answer a question, then one has not got a ROI on the tuition paid. I teach ultrasound classes, and the graduates are expected to pass the national registry exams and find employment. Both these outcomes require the graduate to apply critical thinking. If the graduate cannot do both then there is no ROI.
