Alrighty, I have to know..
I submitted my app 5/31. Just moments after sending it in, I realized that I messed up pretty noticeably on the course information section. In short, I took seventeen (17) AP & IB courses in HS and incidentally listed the "OT Grade" column incorrectly. All course names and credit hours are listed correctly; it is only the grade column which does not line up with my Official Transcript -- which I later realized read "NG" for no grade...
Though I am ready to bite the bullet, I am hoping to ascertain whether I should 100% expect a returned application in the coming days/wks, which I'll need to fix and resubmit. I tried calling AMCAS, but the answering customer service rep made explicit the fact that they were not a member of the verification team. They did say most returned apps are due to credit hour inconsistencies, but mine are grade inconsistencies. Of note, the AP/IB coursework credits were not used nor do they influence my GPA (for obvious reasons) --- AMCAS assigns "P" to AP/IB coursework to indicate this fact.
I have tried searching reddit and here for similar past posts but to no avail. I have come across the 10+ rule for mistakes, but at least one previous poster had their repeated errors (two semesters worth of course entries listed for the wrong year) corrected, and thus, to my understanding, treated as a single mistake (just repeated many times). Other than this isolated incident, returned apps seems to be very uncommon, or, at least, not posted about.
Thanks ahead of time for any possible insight.
