You want to match your needs with what a school has to offer. Colleges look at your whole high school transcript. Take challenging courses at all levels. Remember that class rank and grade point average are cumulative across all four years. Schedule standardized tests well in advance.
Extracurricular activities are an important ingredient in the formula for acceptance.
There are many sources to get information about colleges and financial aid. Look in directories, write to schools, go to college fairs, talk to friends, family, teachers, and counselors. Essays and interviews are important ways you can let the admissions committee see you as a person. Practice and preparation are keys to success in these two areas. Weigh college acceptances carefully.
