I just took the test today. I would say it's challenging, but not too hard if you take the time to read over the material several times, use the test review and know the information listed in the curriculum. Of course I don't know if I passed yet, but will know in a week or so. Aside from the above advice I recommend being familiar with the hunting regs, wildlife in Washington and spend extra time reviewing all booklets produced specifically by the Dept of Fish & Wildlife.
