I have not taken the SAT yet, but my PSAT verbal score was 80 and my math score was 73. I have been heavily involved in extracurricular activites, several of which I hold leadership positions in. I have done a little bit of volunteer work. I work hard, and I believe I am an excellent student, but my GPA does not reflect that. I have several schools in mind that I am interested in attending, but they are highly selective, and I am unsure whether or not my GPA will prevent me from being admitted.
Most colleges look at the high school curriculum of an applying student.
Then they look at the grades in that curriculum. Then they look at the test scores. Some special programs at a college or some scholarship programs may look at test scores sooner. For some, there is a certain GPA that must be met. I think you will benefit from talking personally with admissions representatives at the schools in which you have an interest.
