I guess it depends on the instructor~ When we do challenges here you have no time before hand~ Some instructors have 2 different challenges. 1 is an instructional challenge where they will give you so much time to ask questions and go over a few things with you and then there is the straight challenge where you dont have any time but to do the tests. As for the questions, it varies. Just know the transport and storage laws for both restricted and non, know ACTS & PROVES, know which is the largest diameter for shotuguns and the lengths, know the difference between cartridges(wadcutter, round nose, FMJ...etc) Basically just read the books you got~ The written exams are not the best. The way they have worded some of the questions really make you think but you just have to pick the best of them all. The tests were written awhile back and have not been updated since so make sure you go with what you have learned through out the books and not what you think is right. If you have had a lot of experience with the firearms you shall do fine. If your nervous about the testing part just take the course. Everything they teach in the course is what will be on the tests. Its 50 multiple choice questions. During a full course you have lots of time to fondle and get familiar with the firearms before your practical. All you can do is your best~
