I'm looking for study materials for the 7 & 66 and I've noticed
that most of the books and manuals available are two or three years
old. There are also a lot of used books that are much cheaper in price.
Have the exams changed enough in the past year to justify tracking down
an 05 edition, or will an edition from 2002 or 2003 contain the same
material? Also, are good condition used materials worth the discount?
Any advice would be much appreciated!
