Help for someone with a ~3.5 GPA?

He had a 3.3-3.4 unweighted GPA. His school did not weight, but his weighted GPA was in the 4.0 range, depending on the weighting method (it was over 4.0 for the UCs, for instance). He had a 31 ACT, and a 2060 SAT. He had very good ECs (Student Council, Model UN, JSA/Debate - all for four years, with leadership positions as an upperclassman). He got into UCSD and UC Davis, from out-of-state; Tulane (no $$); Pitzer (no $$); Occidental (met EFC); Whitman ($7500 merit); Willamette ($19k); Eckerd ($19k); Guilford ($15k); and New College of FL ($15k). He was rejected from Berkeley, UNC-CH, and Claremont-McKenna. He was waitlisted at University of Washington and Reed.
