they will consider 700 provided they NOT made a decision already on your app...i am sure they won't wait to issue a decision till your score gets in....if it gets in BEFORE they make a decision - GOOD FOR YOU! if not, then one of 2 things
a) u get placed at the bottom of the pile so that they wait for your scores meanwhile making other decisions first - NOT GOOD since seats fill up!
b) they make a decision based on the score u submitted initially
.... i find it very hard to believe that they will wait patiently for your score to get in at any time AFTER the deadline....the extension of deadline occurs till an unknown date...meaning they could pull the plug anytime!
