Now as an applicant, because I did not have a 310 my process was grueling. It was nonstop worrying about getting the interview. Your main focus should be getting an interview. Call your admissions officer and become best friends and ask this specific question,"what can I do to make my application strong enough to warrant an invite for an interview"? I had to rewrite my essay, get another LOR, retake a prereq, and finally they invited me for interview. But it's because I would not take no for an answer. Be tenacious, never give up.
Now if you have over a 310, a 4.0, and have experience well then the invite should just roll in lol.
