Glad Ed and I got that testing out of our way. Something we learned from these two tests:
turf test - 90% of it is the same thing as core. Study, but mostly look at the turf names and diseases. Lots of disease and insect questions.
ornamental- much more difficult than turf. You are going to have to look at this one long and hard and really soak it in. Lots of disease questions, and a lot more regulation questions than you would think. Math is a gimme on this test. Study Study Study for this one
