My girlfriend took the online course and then we traveled about 2.5 hours to a sportsmen's club in Madison for the field day. The online classes are long and boring, but it's basic common sense stuff. Her field day was a joke. It was some 70 year old men putting 12 year-olds to sleep talking about things unrelated to hunting. There was a written exam and they had to show firearm proficiency. I scored all the written exams since I was there for the day and they were shorthanded.
You would have wanted to look this up around July because you will be hard-pressed to find classes so late in the year. Depending on where you are you can contact the DNR and see if someone locally could adminster the test for you.
