i took the test this summer for hunting and fishing. i actually took 4 tests. 1 for hunting, 1 for fishing, 1 for general guiding, and 1 for boat and canoe use. the tests are mainly regulations and emergency situation questions. they only provide you with the regulations guides (hunting and fishing). they provide you with absolutely nothing really to study. it was suggested to study the bsa fieldbook. i would suggest also reading the regulations guide and general small boat safety info
example questions-
what is the min length for bass in lake champlain?
what is the maximum number of hook points allowed?
the tests are all multiple choice w/ four possible answers.
hope this helps
