College Decisions

<p>When do college decision usually come out by?
ike atleast for these 3 colleges-
like MIT says they'll notify me by March 20th. does that mean i'll get a mail between january and then , or i'll be notified on that specific date?
and the same goes for BU. they say by april 1st.
and UConn says that they start rolling notification from jan 1st. does that mean i may get my acceptance/rejection letter in february or something cool like that?
thanks.</p>
