Does the AUC website ever get updated with regards to open houses?

Yes, they usually keep them fairly up-to-date. They may not have scheduled the Spring Open Houses yet, so they won't have them online. You could call MEIO and they might have info about it, but it usually takes a little while to get the website updated. If you don't feel like calling MEIO, I would look for updates in the next 2-4 weeks for the new open houses. I think they run them mainly in late spring, so possibly late March through early May would be my guess.

Good luck!
