I scored 65, which the test calls High Mach(iavellian). I don't put much trust in the test, though, because the questions are all generalizations and it's easy to come down on either side of most of them.

Machiavelli himself might not have believed many of the things he wrote. After all, he wrote his principal text, The Prince, as what was essentially a job application letter to a despotic Italian Renaissance ruler. Since he was unemployed at the time and desperately seeking a position as an advisor in that prince's court, he could have simply written what he imagined that very self-interested and fearful ruler believed.
It was perhaps rather good advice to a insecure autocrat lording over a small city state, at a time when most such politicians left office quite precipitously, and feet first.
