The general consensus is to get your app in as soon as you can. If there is a real reason why you can't (LOR, etc), then you obviously don't have a choice. However, it is always better to wait a few days than submit a rushed application. Do not rush inputting info, writing essays, etc so that you can get submitted day 1. Your application won't seem polished and could hurt your chances at interviews.Is there a difference between submitting your primary application on May, 28th vs. mid June? I know that to some extent that applications are rolling but, aren't primary applications sent at one time to medical schools in July? Do medical schools receive applications in the order that they are submitted and does that matter? Thanks!
