Recent Student Evaluations:

  • The discussion board questions were one of the most helpful parts of the class, aside from the material that was shared by the Professors.  It was very beneficial to get different perspectives about what others around the country and world get to deal with.
  • Learning about the specific structural analysis of the transmission structures was the favorite part.  Least favorite would be performing the time consuming calculations.
  • My favorite part of the course was getting an inside view of the fundamental principles.  For too long have I been curious as to how and why we do some of the things that we do.  Now with classes like this the understanding grows and more questions get uncovered.
