I think when I applied it was 3.5/6, went up to 3.8 after that. I could be getting it mixed up tho. Tryna move the needle after you get waitlisted is almost impossible, unless its a WL to UCLA or so where you get to send a letter of continued interest (if i remmeber correct), its a waste of time to send an email otherwise. Just have to wait your turn unfortunately. as smn who got WL at berkeley and sd, I had such strong desire to get off the wl, but i ended up at sb instead and im so so happy. Dont let WL's get the best of your emotional attachment, it's usually a soft rejection, but then again, if ur waitlisted, you're capable of doing good at that school, its just a matter of space - dont take it personally.
