With all due respect, passing the test IS the point of this thread. Our friend who started it isn't concerned about debating "how many comparable sales can be regressed to the head of a pin", but is concerned about passing the @!$& cert exam, which is not easy. "Teaching passing the test" IS what all good prep courses do - whether you are talking Bar Exam or Appraisal Exam.
My conviction re: Hondros stems from my own experience of taking Bruce Legg's seminar, which uses them. I took the Cert. test 16 years after becoming an appraiser and 9 years after taking the 50 upgrade credits. (By which time I had little memory of the earlier classes and coursework). In addition, my math skills are, shall we say, not the best and leave it at that. Using Hondros I passed the cert. test on the first try. So yes, I will swear by it. The certification test was - BY FAR - the most difficult exam I have ever taken in my life (and I have passed the Bar Exam, which is no joke either).
