Regrettably, I did not save electronic copies of the first two years of the program - perhaps one day you will encounter them somewhere in Greg and Yan's syslab accounts. Also included here is a long list of interesting problems (without solutions) that were used as IMO preparation for Yan Zhang in 2003. (Note that for some stupid reason, I used the convention of beginning 2005 TJUSAMOs with 2004TJUSAMO*.*)
