The game adds a personality system for your hero, which determines your stat increases at level up. Getting a good personality early on is pretty important, although I don't remember how to do so. Trying oddball things, such as refusing to visit the king in the intro or saying you were rude to him, will change your personality into oddball ones.
IIRC, there was very little correlation between the decisions you make in the test and the personality you end up with. You just run through the test randomly and get a random personality. Then you can look online to see if your personality is good or bad, because the personality's name doesn't really make it clear if it's good or bad, and restart if you don't like it. But if you're looking at guides online, it's easiest just to look and see which personalities are the best, and exactly what you need to do to get it.
IIRC, the statistically-greatest well-rounded personality was the Sexy Female, but other personalities could be more effective if you were looking to target certain attributes.
