Hey there, definitely retake your GRE . I know I know the thought of it is a nightmare trust me I have taken it multiple times last year I got a 297 was so happy about it but they said that is why I didn't get accepted after my interview because everyone else who interviewed had over 300
broken heart u can imagine , therefore I am retaking my GRE next week. Yes I know its passed deadline, however, because St. Augustine is rolling admission it does not matter. For Austin campus there will be two rounds of interviews held. My adviser told me not to worry about the date being after deadline, that if I get an interview I'll be with the second round.... Anyways I hope this helps, its worth re-trying. AND is your application states "re-taking" GRE it'll look better on you.
