I always thought AP exams weren't fair to NY students. Because our school year started later, we had a month less of instruction than students in other states. Then tried to use the last month to prep for the NY regents exam which often contained totally different material.
As for funding, if you get into many private schools, aid is based on need as much as merit. Keep that in mind.
1. Yes, I realized the same thing about NY and AP. We moved from NY to another state last year. This year even though school here starts two weeks earlier, they had a few days of "summer camp" to get a jump start on the AP classes so they could finish in time for the exams.
2. That is absolutely true. Yes, you need the grades/scores/rank to get accepted to the top schools, but a good number of them do not offer ANY merit based scholarships-- need based grants are all they offer regardless of how great of a student you are.
