If you're really not sure, just get down below 3000' or 1000' AGL and make sure your wingtip misses.....
Probably not a good idea in a test. Too hard to navigate and too dangerous. Lots of well qualified pilots use and abuse this rule far too often. This rule is only intended for a short hop or to get out of trouble.
You will do well in your test because you are already planning for the possibilities. The golden rule is don't take the plane anywhere you haven't been in your mind at least 10 minutes ago and always have a reason for going there!!
Good luck.
