Oh, and you don't really have to take it all in one sitting, so if you don't finish in a certain amount of time, you can finish it at another time. It isn't time-contingent. It's just long, boring, and highly repetitive. Just takes the time to sit and answer the around 400-ish questions (can't remember the exact number, not that it really matters; it's a lot). Seems like it took me around an hour. I think my son took about the same. These aren't questions you really have to spend much time dwelling on or anything.
