I noticed that the submission date is May 4th and that typically submitting early is beneficial. But I noticed that schools do not process the applications until June 15th. Will it matter what time I submit everything in as long as it is within that period of time?
I submitted really late in the cycle (after the new year actually) & still received an interview invite so anything is possible, but my MCAT was higher than yours so the earlier you apply, obviously the better. A score of ~500 is below the accepted averages for DO schools but people can get in with that if the other components of your application compensate (better GPA, extracurrics, something that makes you stand out to adcom, etc.)
