Well, congrats to you are definitely in order. I didn't get accepted or waitlisted for Centralia, so you must have had a solid application and course package, good on you. As.for the provisional acceptance, I can only think that means that there are still sole hoops you have to jump through; IE, submission of official transcripts, immunizations, and background check. My guess is, it's a provisional acceptance until you finish all those things and don't get hung up anywhere in that process. Regardless, congrats, now the real work starts.
