My WSDA license is good in this state, Oregon, Idaho....with just a form.
They offer 3 day courses with testing on 2nd half of the 3rd day. We buy all our own study materials, also. The AQUATICS PCO is SUPER hard. They're not gonna let ANYONE spray near SALMON RUNS.
Each test has around 65 - 100 questions....me being of above average intelligence finishes early. The city types and the like race the deadline....
