Funding for Pre-Law

I am 17 years old from Trinidad. I have worked relentlessly to achieve my goal of attending UWI st augustine to pursue law. I recently got accepted into the Pre-Law program which GATE does not cover, and I am trying to find ways to fund my education. My mother doesn’t believe I am fit to be let out into “the real world” but I believe I’m old enough to learn about what the real world is like. If I can raise the money I need for school, I can more than prove I am capable of getting somewhere with the resources I have. I want to prove that I can make it, but I need the funds to show it.
