I went to Ivy Aspire, they were pretty good and helpful. You should maybe check them out. Shaista the owner herself is an Ivy League pass out and has been on the admissions board for many colleges. She takes personal interest in each student and helps out individually. the center also provide lot of help with other classes such as GMAT, GRE, AP Exams and so much more. Along with SAT i also took up the undergraduate counselling, it was just awesome.
