I'll say I'm a 7, maybe an 8 on a good day. I won the Star Wars trivia challenge at the Fantasy Flight Star Wars Gaming Event in May, so that's worth maybe a six. I've got a lot of versions of the Star Wars RPG and obsessively read pretty much all the novels up until the execrable Swarm War trilogy (apologies to Troy Denning). After that I just didn't bother to keep up much with the EU. I sporadically keep up with the Old Republic events and was mildly interested in the Clone Wars cartoon. I love what Dark Horse has done with Star Wars. Then again, I read Wookieepedia and realize that getting a 10 would be impossible for anyone, with the exception of George Lucas or Steve Sansweet!

After reading through the responses I am dropping myself to a 6. I had forgot about the old republic and legacy comics stuff which I know very little about.

Five. I know a little bit beyond the classic trilogy, but not enough to rate myself a six. As for the EU, here are huge gaps in my knowledge.
