It’s very simple to be honest. My youngest just finished his at 9 years old and my oldest got his when he was 8.

Know the regulations, read through all the rules, lots of gun safety, a little bit about different types of land, what creates good habitat, animal identification mostly what’s a moose vs an elk or a whitetail deer vs mule deer.
Then plenty of just common sense stuff.
Both my kids got 100% on their tests so don’t screw it up!
