I would urge you to use these podcasts as supplementary material for a Princeton Review, Barron’s or Kaplan’s Study Guide to the Graduate Record Exam (General).  Don’t fret over which publisher, just get one!

Note:  Writing credit for the definitions goes to one, if not all, the publishers listed above.  I will admit to some shoddy record keeping as they were intended for personal use.  I remember getting the list from a website that listed one of these three books as a source.  If you find these useful, please consider purchasing one of them from the link below.
