Is it better to knock more balls off the poles, and do the crane practical exam test course fast, or is it better to take my time and not knock over anything.

This is a difficult question to answer. We have seen crane operators knock over a lot of things with fast times and pass. And we have seen crane operators not knock anything over but take too long and fail. There if a balance. The best thing to do is stay within the time limits (try not to knock anything over.)
