British titles are complicated and obscure, but they're not impossible to get right. I got the basic jist of them within a few weeks of coming into the fandom.

(Side note: I've seen it suggested that the oh-so-complicated nature of the titles is like a shibboleth used to identify the people who belong to the group and those who don't. Obviously it's possible for an outsider to figure it out too, but if you screw up the titles it's a pretty obvious indication to the aristocracy that you are not One Of Them.)
