Where do I look for more scholarships once I get to college to help with the remaining school years?

Imani, every year you'll fill out the federal financial aid form, FASFA, https://fafsa.ed.gov/. Every year your college/university's financial aid office will evaluate your need and allot you what funds they are able to allot to you. This is the case for big federal grants, state grants, etc.

Here's also a little secret, the school has grants/scholarships which are exclusive to them, from their alumni. Financial aid offices will evaluate your need and your performance at school to decide if you are a worthy recipient. A big part of that evaluation is your relationship with your professors. If the grant is specific to a major then your professors will be asked, "Which one of your students would you think best benefits from a grant like this?" Do your best to make your work, your participation, and your interaction with your professors something that makes your professor answer that question with your name as their answer.

Spend some time looking at https://fafsa.ed.gov/ and https://myscholly.com/ to keep up with your options as you progress towards your degree. Rest assured though, there is money available to help you every year you are a student, all the way up to a Ph.D!
