In the past, only Honors kids could choose Landis. You can call and ask Honors for their exact answer to be safe, I don’t want to give you bad advice. However, Landis has approximately 400 beds. Not many upperclassmen stay there - most would rather go to apartment style dorms like Ragans or Traditions or go off campus. I would think most Honors kids will safely get a spot in Landis if they want it.
Also - I think you will lose your priority number if you don’t pay the $225 by today? Are you thinking you’d resubmit your application again after the 28th?
