I agree with this. I've just received an email from  my professor, implying me not to take it. He suggests me  the strategies for building portfolio my own way(such as setting up studio..) . Sorry, I am talking about my situation here too much. SAIC offered me "prior degree program" , not the recommendation  to apply for their post-bacc(I don't think they are same). Anyway, I was rather positive on this option until my professor's email since I don't have much options for MFA this time. I only applied three schools to save the application fees; I know I wasn't ready  this time(I even included  my first oil painting to fill the minimum images they require). I am still not  totally decided yet whether I take this offer or not. But if I do,it will be only for a semester, which I think is enough time for me to develop better portfolio without risking my financial status.  
But I don't think you need to consider this option much since you have already a couple of interviews waiting for you.
