85% is pretty good, given how many of the questions are trick questions. It works like this (at least in Missouri): they throw in enough tricky asinine questions that you must know 100% of the simple answers in order to pass.
My favorite is where they ask you to calculate the volume of a conical tree...like that had anything to do with how to spray one! I have looked all over, and I have never found any spray application that uses any calculation of the volume of a tree for any dosage or treatment related application. Another one is about roundworms, and references their phylum; they actually expect you to write down the incorrect answer in order to get that one scored properly.
I haven't ever taken any CEU's, nor any review courses. I just take the test every three years, since 1984.
I have taken the test so many times, the examiners have even greeted me by my first name when I walk in the door.
- The CEU's cost lots of money, the test is $45.00
- I can take the test and be done in 4 hours, including drive time; the refresher courses take two days.
- The test really hasn't changed that much over the years; I know most of the questions by memory.

I will not worry about the CEUs either.....just take the re-take the test.....most of it is common sense and yes, there are the few trick questions to get you guessing....I figured there is no way I would miss 20 of the 80 questions.....lot of math questions and math is one of my strong points.....however...I can get CEUs for my CA license and my pesticide now so it may not be a big deal. It seems as if they just want you to go through the process to make sure you are serious. I did like going to Purdue to take the course and test in late summer.
