The short answer is that you are not too late. PTCAS sends emails to let you know when deadlines are approaching, and I believe only one or two schools have elapsed deadlines right now. More importantly though, you need to check the deadlines for the particular schools you are looking at, since deadlines vary a great deal.
I don't think you're chances will be hurt at all as long as you:
- Work on the PTCAS application ASAP if you haven't already. I was surprised how long it took to fill out!
- Give a friendly reminder phone call to your recommenders. PTCAS will actually forward your application to schools and send the recommendations later so that they don't hold up your application.
- Request that your transcripts be sent ASAP if you haven't done so already. PTCAS will not forward your application to schools without these, and they actually take a few days comparing your transcript to your application. You don't want that to be what's holding things up.
And Good Luck! I submitted last week, and now I'm just waiting... and waiting...
