I'm in the exact same situation. I submitted my scholarship form for SVA fine arts mfa but the impending SAIC deadline with guaranteed funding attached is tempting. I have an offer from RISD as well with some funding but not quite as much as SAIC. It's frustrating to have to decide before all the information is clear but maybe it's just an early bird gets the worm situation for SAIC. Have you done any more thinking on the matter?
