Hi, I submitted my TMDSAS application back in June, one of my letters of rec though still hasnt been submitted yet. It's my graduate adviser/previous professor/associate VP for Research. I'm really worried about it since I've heard that schools won't even look at your application until all the supplementals are in. Is it basically like a line and I get put in place whenever my last letter of rec comes in? That's the ONLY thing that's missing right now and I've reminded him a few times already. He's just really busy right now it seems.
