The thing to remember is that most of the objects will have a pair. By this, we mean that there will be common items, like a pen, and a pencil, where if you can remember one, it will help you to remember the other. In some cases a whole series can be formed, like Pen, Pencil, Rubber, Pencil Sharpener, Paper, Biro, Ink, etc.
All these have the same common root — they are used when writing. So the more you can connect, the easier it should be. One of the best ways of getting used to Kim's game, is to walk slowly past a shop window, looking at all there is on display. Go past, write it down (or describe it to a friend who is looking in the window at the time), and go back and check the list. The more you do it, the easier it will become. Read the stories of Kimball O'Hara and the Elsdon murder at the beginning of Scouting for Boys.
You may not be good at this test to start with because you have to train yourself. Remember you also have other senses which need training.
Alternatively follow a trail containing not less than 30 woodcraft signs.
You will have learnt several woodcraft signs for your Tenderfoot test and you probably followed a short trail.
Now for Second Class this should be a test of observation. The trail may be marked by leaves or twigs placed
in strange positions i.e. an oak leaf may be stuck among some horse chestnut leaves, or pieces of coloured wool may be draped over bushes or on the bark of trees.
Remember that the trail should only be obvious to Scouts and should be cleared away once it is finished with.
