Below are select audio files of Precal.  We began recording classes with chapter 9, conic sections.  I try to choose my words carefully so that these recordings will be helpful to the student that missed class.  However, I am still learning how to explain a topic and at the same time, remember that someone listening will need more descriptive words than what I am used to giving.  Please advise me of any corrections, criticisms, and improvements that need to be made. 

Parents:  I would love to have your feedback as well.
