Chill is my middle name 😎
It depends on the person. I was pretty lax about my submit date (Aug 1). I took my MCAT at the end of May so I was busy studying during May, and I probably didn't even start filling out the AMCAS until after June 1, my year's submit date. Then I was working full time after taking the MCAT so it took me a while to get all the stuff written for the application and overhauling my PS. I wasn't an early applicant, but I wasn't late either. Sure I kinda wish I had gotten it out earlier so I didn't have to do as much waiting, but it all turned out great. I don't mind the people that want to be on top of things and get it out first thing, more power to them, but the people who stress out about submitting it at 5pm June 10 vs 9:30am? Or an AMCAS server delay that is out of their control? Come on. You'll experience a lot of "bummers" during the app season, this really is a minor one.
