Thank you for all your advice! I have a few specific questions

My son has high SAT, ACT, AP(all 5s), and 4.0/4.0 (unweighted). He attended three-four clubs so far and has state awards. However, he is not a captain of any. He is much younger than his peers (this is my excuse :)). He has a good heart and likes to help others (peer mediator, mentor of junior graders).

He is a junior now. What suggestion may you give to us? My son also wants to go B schools.

Thank you a bunch!
