Hi,
I am not a reapplicant, but I am also taking the OAT in February for Fall 2007 admission. I called all of the schools that I have applied to (SUNY, PCO, ICO, NOVA, and NECO) and they will all accept my OAT scores as long as it is before the deadline. However, I only have 1 shot on the OAT because I can not take the exam again after 90 days and still make the deadline. SUNY has the first deadline of February 28th so I will definitely be taking the OAT before then.
I feel your pain - I am extremely nervous about the OAT too - good luck!
