TreeAce,
I read A New Tree Biology, and companion dictionary, ISA study Guide,with urban forestry, the set of 10 Interactive ISA dvds,Borrowed, and the A 300 on prunning,Shigo's is CODIT and that helped but Dr Shigo explains and reexplains definitions which are correct, yet still not addopted in the ISA that probably hurt me a little. I love his definitions, I had the book library loaned from TTech in Lubeck and had to extend the ck out 2 weeks twice, 676pg,plus dictionary I may buy this set too,
What happened is I would take Shigos side, and argue the question as invalid, Which it may have been, in other words answer the questions dont fix them, I wish I had studied more on tree ID was told they would have latin and common, but at least three had only Latin, any way after the test I looked up some that I remembered missing, this site for texas trees, makes good commode lit too,
also there were some OSHA questions that arent in Z133 about HAZCOM since I am not a pest or fert aplicator wasn't familiar with this, you can google HAZCOM and read and read lawer liped pages
also found some Practice quizes online too, the practice quizes all had three Wrongs and a Right
the real test had two wrongs and two grays, on a lotdid better than I thought tree ID at 77% brought me down to an 88 overall.
Since the study guide is written by Lilly I would look at some of the other Lilly books too,
