If I'm waitlisted, do they need to see my quarter grades?

Got waitlisted by some schools, particularly WUSTL and Brown. I know getting off the waitlist is a longshot, especially for the former. However, my question is…would they require me to send in my 3rd quarter grades? Or my second semester grades? Honestly I didn’t have such a hot 3rd quarter so those might sink my chances… x.x

Sorry I’m bumping this… I’m trying to look for threads addressing this question but I can’t find any D:

The best way to know is to ask the school itself.
