I dont recommend challenging. There's a lot of good info that can be had thats not in the book. You cant ask a book questions. Your core intructor will be able to direct to lots of resources that the book will not.
Plus its a good way to hook up with other new hunters.
If you were an oldtimer hunter who let his hu ting stuff laps then maybe you should challenge but newbs really should put aside the time to do it right.
