Here is a quote from the admissions advice page:

“What does matter in the admissions process? Yale is above all an academic institution, and thus academic strength is our first consideration in evaluating any candidate. The single most important document in the application is the high school transcript, which tells us a great deal about a student’s academic motivation and performance over time. We look for students who have consistently taken a broad range of challenging courses in high school and done well in them. There are no score cutoffs for standardized tests: the median scores for admitted students on the verbal and mathematical portions of the SAT generally fall in the low-to-mid 700s, and the ACT composites in the low 30s, but successful candidates present a wide range of test results. While there is no hard and fast rule, it is safe to say that performance in school is relatively more important than testing. A very strong performance in a demanding college preparatory program may compensate for modest standardized test scores, but it is unlikely that high standardized test scores will persuade the admissions committee to disregard an undistinguished secondary-school record.”

This is from the second link.

There is not a set precedent against a public high school. 85% of my high school class went to college, many of us were accepted at ‘elite’ colleges and universities. Your performance is the most important thing. The SAT or ACT helps establish that your high school education was equivalent to any other school. Some schools, Stanford for one, have a formula that allows a person with a low GPA to score high on the SAT or ACT and still qualify. They also expect a better SAT or ACT for students with a high GPA.

The fact that you are starting now indicates that you should do well wherever you go.

The thing to remember is that after your first job, where you went to college is not as important as the quality of the work you do. The quality of an education always depends on the student. Schools are storehouses of knowledge, the students bring it in and usually leave it there!

Good Luck

I know they like people who are good writers, so make sure you keep working on writing.. they want very high scores on the ACT writing test..
