For Yale and HBS, as they said officially, your score of May, 2002 is expired since they consider it must valid untill you enroll in August. However, i do know a guy who got in Yale this yr with a score taken in Jan, 2001.
So, for sure, you'd better ask ADCOM to confirm. The bellow is the answer i have got from some school, (my test was taken in Jan 2002) hope it can help you all.
FYI:
第一种情况: YALE(要到8月的), HBS(要到九月入学)、 UIUC
第二种:(The Toefl is valid for two years from the date you took the exam to the date you submit your application.只能用到递交申请之日):WHARTON, COLUMBIA,CHICAGO,IOWA,TUCK, Mich 另外,只能用于第一轮:INDIANA(只能用于第一轮12。1),
第三种:能用的NYU, DARDEN, SIMMON, ADERSON, UBC, CAMBRIDGE, LBS,Oxford |
