When I took it at the DNR in Annapolis they told me I could take the NYS test or the old federal exam. I took the fed test and some of the questions were really quite outdated and included some things on diet that I disagreed with (but don't remember specifics now). It was, however, very easy.
The person who administered my test was Mary Goldie mgoldie@dnr.state.md.us and I have emailed her about various other permitting questions; she is very helpful.
