I highly recommend attending and taking the Deer Hunter's Education classes- they typically are a day and a half long (at least here in Missouri they are). Their goal is to get everyone passed, so don't stress about it.
Not trying to say you're old.... but you may check into the laws your state has about this requirement- here in Missouri if you were born before 1967, you are "grandfathered" in and do not have to take the Hunter Ed. Course if you don't want to
