is there any financial aid?

Answered

The process of applying for financial aid involves filling out a couple of online applications. First, all schools will require the FAFSA (https://studentaid.gov/h/apply-for-aid/fafsa) for students who are US citizens or permanent residents (international students don't qualify for federal aid). Second, some private schools, including Colgate, require a secondary application called the CSS Profile (https://cssprofile.collegeboard.org/) which is run by College Board. Both of these applications should take no more than a couple of hours; they require detailed financial information, but beyond that shouldn't be overly complicated.

If you did not fill these out in the fall/winter, it's likely past the deadlines for Colgate at this point, but financial aid offices will often be flexible with students who were unfamiliar with the process. You should go through the steps that @whynir mentioned to contact their financial aid office and ask if you can still fill these out, even if you don't think you qualify for financial aid. Once you get an offer back from them—even if that offer is for nothing—you can then appeal based on special circumstances. In any case, these are all conversations to have with their financial aid office.
