after reviewing the site at Cornell, the way the letter is written, the "reserve list" letter I received sounds like what Cornell calls a hold. I realize that this is merely semantics, but if it helps any...
taken from their website:
"At Cornell Law, if we have given you a decision of hold, it means that we have reviewed your application, but we have not reached a final decision of admit or deny on your application. We will review your application at least one more time before reaching a final decision.
You may submit additional information to support your application as you are waiting for the final decision. Typically, applicants submit additional grades, new honors or promotions or an additional letter of recommendation.
At the beginning of the summer, we review all the applicants still on hold and create a summer waitlist.
If I am on hold, when will I receive a decision?
Applicants who are placed on Early Action Hold are reviewed after February 1 and typically receive a decision (admit, deny or hold) in February or March.
Applicants who are placed on Regular Decision Hold typically receive a decision (admit, deny, or summer waitlist) by late-May to mid June."
