I concur. Most employers doing GW OCI know the system, so they ask for top 15%, top third and top half - aka, the only things it's possible to figure out. Btw, as far as I know the curve is still at 3.0, maybe a little more, but not over 3.1. If some employer at an outside job fair asks for "top 25%" or something, just explain the system, and I'm pretty sure they won't care if you're top 35% instead of 25%. If you are just trying to figure out whether you're at 4% vs. 6%, go away.
what does "diaf" mean?
also, i'd like to figure it out with greater precision than merely 15% and 35% because i'm considering transferring, and it seems like the only way to meaningfully weigh my options is by knowing my rank.
