Low Income + What if I can’t afford?

Yeah, I understand that FAFSA is based on eligibility and since I come from a pretty low income family, I’m assuming I’ll get something. Also yes, earlier I said I’ll be taking the SAT 2x and I’m taking the ACT in 2 weeks. I have considered some other VA colleges but I’m not in love with them as much as VT. I have one school that’s commuting distance but I don’t like their school as much (defiantly a back up) or their campus. I do not really like that school and I want to go somewhere where I’ll enjoy for the next 4 years (If I stick to Dentistry, I’m most likely going to their Dental School since its the only cheapish, good school in VA so I don’t want to be there for 8 years of my life). I’m just asking is there any way I could get a lot of money without being in debt from undergrad? Best places to find scholarships or specifically for VT?
Thank you!
