选校，EA or ED?

小中男, SAT 23５0, GPA 4.0 unweighted, rank 1/400, 7 AP, all 5, 4 subject SAT, one 780, three 800

其他EC一般，two school sports, one of them is varsity,  leader in couple of small clubs, a little bit volunteering, and a little bit summer research experience at local lab,  无竞赛大奖。

No dream school,  he wants to EA big ivy but parents want him to ED Dartmouth/Brown/Duke.

Please help, thanks!
