有关邮寄日期,COMAP的官网上这么说
When must we mail the solution papers?
Papers should be mailed in time to arrive at COMAP no later than 5 pm on Monday February 16, 2004. COMAP cannot reply to queries as to the status a paper's arrival. We recommend that papers be sent via a carrier that allows packages to be tracked. Advisors can also login to the MCM web site to verify that COMAP has received their team's paper.
