Oh man... after all four rounds are over? I thought in the email they say evaluate over March to July...
"It is difficult for us to provide specific probability of admission or the timing of a final decision as the timeframe does vary. Applications can be re-reviewed by the Admissions Committee at any time, but this typically happens between March and July. Applicants may be offered admission, their waitlist status may be extended or they may be released and encouraged to reapply the following year."
... if it really is at the very end, that makes it so much harder
