yes I believe they start off by offering 20,000/yr to a few of their top applicants, usually people with no lower than a 3.8 and 20's on all sections. Then if these applicants turn down the scholarships they break them up into 10,000/yr offers and give it to a larger number of applicants who almost met the standards (my friend and i got offered the 10,000 and we had 3.8+ but less than 20 on one or two DAT sections.) if any of those are not accepted, they filter down to the next level of applicants, etc. I am not sure if they are broken down into smaller increments at that point or not. as for the timing, I think the 20,000 offers come at the same time as your acceptance, while the 10,000 offers may come weeks or months later (I got mine like 2 months later). you must maintain a 3.5 gpa in dental school to be able to renew the scholarship each year.
