<p>Yes. For applying for financial aid, colleges require that you submit a FAFSA form, which is a federal government form that can be found at <a href="http://www.fafsa.ed.gov%5B/url%5D">www.fafsa.ed.gov</a>. Many, particularly those who may provide aid in addition to what the federal government funds, also require a CSS/Profile form which you will find at <a href="http://www.collegeboard.com/article/0,3868,6-30-0-8374,00.html%5B/url%5D">http://www.collegeboard.com/article/0,3868,6-30-0-8374,00.html</a>. Some colleges also have their own additional forms that need to be provided which you can usually find on their websites.</p>
<p>You should check with each college to which you are applying for its requirements for submission of the forms, particularly to determine whether the CSS (or a college's own form) is required and the date by which you need to submit the FAFSA and any other required forms. That information can easily be found for a college in the admissions section of its website and the page that is usually indexed as "financial aid."</p>
<p>Submitting the common app is only the beginning to applying to a college. You need to go to each college's site and see what supplementary forms need to be submitted not just for financial aid but for admission in general.</p>
