The software places you with your best category, that is, if you had a single acceptance, that is the bin where you are allocated. In general, MA>AC>IN>RS>RJ
MA=matriculated, AC=accepted, IN=interview, RS=Request Secondary, RJ= Rejected. There are other potential final choices such as WA=Withdrew After AC, or WB=Withdrew Before AC, and I am lumping PR (Preliminary Rejection) with RJ because it makes no significant difference. There are other temporary choices that some schools utilize such as Hold (HO) and Alternate (AL). Later in the cycle, I will be talking about those who are in the AL category. Those will be in the National waitlist. Almost at the very end, every year, some schools will take an applicant who was interviewed and allocated to PR/RJ, and give them an AC.
The entire process is nerve-wracking for applicants, but also for Program Directors. We are trying to fit a relatively small class. We don't know if we are overshooting or undershooting in our projections. I try to be realistic and provide feedback in my own Exit interviews, and while I am told some times that I am too harsh/brutal in my assessments, some of those applicants use the feedback constructively to get into outstanding programs.
Those of you with interviews at this point must feel reasonably optimistic that one of these MD/PhD programs will take you. You are not competing against 1765 other applicants but truly against 891 other applicants and by the end of the cycle, around 770-790 will receive at least one MD/PhD acceptance. That is pretty good odds...
