This was the advice I received from my pre health advisors in mid may/early June. First secondary was send out 9/3. I'm really glad I took the time to shore up my primary and secondary essays, especially with lowerish stats (513, 3.2 gpa) but a compelling story/reinvention.
There's a lot I didn't understand about the timeline of this application process going into it as a nontrad. In hindsight I wish I was in a position to submit about a month prior. The potential to forego some neuroticism by hearing back earlier is definitely something that shouldn't be taken for granted.
It was very stressful for a while seeing people having II's before I'd sent out a single secondary. The waiting is brutal, so I feel you. I'm fortunate to have heard back quickly from a couple of schools, but am still radio silent from almost 20 of them.
THAT BEING SAID it's a very long cycle and I dont think aug/sep is "late" by any means (with the exception of like mich and pitt). Outside of the big R waves it feels like it's been pretty quiet across the board. Now that we're entering the next phase, we should be hearing back soon!! (copium)
