Am I able to take a CCW class before turning 21 in Wisconsin?

Hello all, I just have a quick question. I turn 21 on April 18th, however the closest date for a CCW class after April 18th is May 16th. I would rather not wait a month to take it after I turn 21, and there is a class on April 13th near me. Do you know if I am able to take it under 21 in Wisconsin if I am 20 years old? via /r/CCW http://bit.ly/2OSX6fv
