I have just received my study material to prepare me to take Ohio's commercial applicators exam. The 3 fields I will be tested in is core, turf, and ornamentals. Other than looking over the material, what is the best way to study for this exam. There is a new applicator training day March 17 in Reynoldsburg that I am thinking about attending. If anyone has any feedback on how well the classes prepared you, it would be appreciated. Thanks.
