So, does the date you submit your application affect it? For example, I turned mine in October 31st for ED, would that affect my chances? Would it have been better to send it before?
Unless it’s rolling admissions, then no, it doesn’t matter whether you’re early or the last minute. I would not suggest anyone wait until the last minute, though. We’ve heard stories of crashed internet, power outages, and very slow servers, none of which competitive schools accept as an excuse.
