Is there anything else (other than College Board and the Common App) you need to apply to college?
A credit card. You’ll need money for application fees and fees for sending test results to each college, or you’ll need to apply for fee waivers.
Many colleges also want letters from teachers and guidance counselors.
Virtually every college lists its requirements on its admissions page. The requirements vary from school to school. I suggest you look up each college you are interested in applying to and find out what is needed.
