As @International_Dad wrote - you are not international.
That is a VERY good thing. First of all, acceptance rate is higher. Second, most need-blind colleges are only need blind for US students, and finally, financial aid is much more available for US students than for internationals.
It also means that you are eligible for aid at any college which provides aid for OOS students.
To make it easier for people (and for yourself) to figure out the best choices for you, calculate you GPA. If your school has grade deflation, colleges will know that. The only issues is with colleges that provide merit aid - they often do not take grade inflation into consideration for merit awards that are based on GPA.
AP courses for which you self studies, and for which you did not receive a grade are not really considered by colleges in the USA. They may help you place, or even reduce your course load if you are accepted, but they do not help your application. Unless you are applying to universities in the UK, self-studying for AP tests is not a good way to spend your time and energy.
Both Film and CS are highly competitive majors, especially at the most popular colleges.
So USC and NYU are considered as having the “best” film programs, but their admissions rates into film are extremely low, and NYU is notoriously stingy with financial aid.
Other great film schools are Loyola Marymount, Emerson, Chapman, and others. However, many have low acceptance rates, and applicants whose GPAs aren’t within the range that they are looking for are not competitive.
You could also look at majoring in digital media. SO CMU is one of the best for that, but has low acceptance rates. However, there are many more colleges with that major.
Which brings us to: what else are you looking for in a college? Urban\suburban/rural?
Liberal arts college or research university?
Size?
Type of students (nerdy/athletic/outdoorsy/quirky, etc - these are not mutually exclusive many colleges have quirky athletes or preppy geeks)?
because you are an American citizen, you have many more choices than your classmates who do not have American citizenship.
