Posted this in pre-allo, but few replies. I was rejected post-interview at the only two schools I got IIs from. I won't be reapplying until 2018 and will work on improving my app. I graduated from undergrad in 2013 and did a post-bac until 2015. I can get a new post-bac committee letter no problem, but the support letters that they include will be 3-4 years old by 2018.
I'm mainly worried about the academic LORs because I have kept in touch with them ever since they wrote my letters, but they haven't been responsive. For example, I asked a professor if she could write me an LOR for this program I applied for, but she did not respond after numerous attempts to reach out. I would stop by their office hours, but they are normally very prompt in replying to emails so I don't want them to update my letters with anything negative.
I can garner new LORs from my EC/work, but would old academic letters hurt my app? Does a new committee letter date overshadow a few old support letters included? I haven't taken a class in 2 years, so should I take one and try to cultivate a letter from that?
