@ethellou: Based on your posting history; Rejected at UCs, CMU, WashU, UVA, Wesleyan, etc…
So you cannot blame “Admission by examination” as the cause of your rejection. None of the other schools you posted about use this method, so it means your GPA among other aspects of your application did not meet the criteria for admission. All you can do now is possibly take a Gap year, regroup and reapply to some more realistic schools with the stats you have. You are not the only applicant has been rejected by many schools. Learn from your mistakes since you are obviously a very intelligent applicant based on your test scores. Don’t blame the system, you need to understand the system to make it work for you.
