On my recent report card I had all B's, one A, and an F in Algebra II. This stuff is so useless and makes no sense whatsoever. I am glad I have been exposed to it but in reality you can only use this in theory, IMHO. I asked my father, who is an appraiser and has a widely recognized reputation for being one of the best in the area, if he ever uses this and he said no. My mom said the same thing, but I can expect it coming from a supervisor of clerks. Unless I am going to be a rocket scientist or somebody who is an author of math books, then this is ultimately useless. Do I stand alone here?
