You can be asked to identify just about any track – bird, insect, mammal, anything, so get squinting close to the ground and try to learn all the tracks that you can. A good field guide and discussions with other trackers will speed up this process. It’ll obviously help if you can get to learn the tracks in the area you plan to be evaluated in. As for the following part of the practical, just keep on practicing on animals you feel you are capable of finding and don’t give up if the trail seems to disappear. Again, it’ll help if you can go out with a more experienced tracker but make sure he lets you do most of the work!
