Did the CPL skills test a month ago, in the test all they will ask you to do is track a VOR on a given radial. This involves tuning in, checking the morse is the correct code for the VOR, and then picking up the radial and flying it.
The VOR can be simulated using the GPS if one isn't available I gather.
If you are comfortable with this you really don't need to spend any time on it during the traing it's about the most straighforward part of the test
I have attached a link to a neat little VOR simulator
