LOL! I think <img src="/ubbthreads/images/graemlins/delight.gif" alt="" /> my problem was that I didn't realize you "prompted" the questions by going close to the teleporters, as opposed to touching them. I kept activating the teleps. and ending up in the following room, throwing the sequence off.

I went back to an earlier save and copped the full XP value.
Thanks all!
