D3 Amount of merit $, can you get a full-ride?

He is going to be a biology major as he wants to go to med school eventually. He likes the small schools better. I don’t think d1 is a good fit as most of those players cannot have such rigorous courses. Everyone tells us that college athletics is a job and I know his gpa would suffer at d1. He is not willing to have his academics suffer for Basketball. I have focused on d2 and naia at this point by checking the surrounding states (we live in Arkansas) school Basketball rosters to see if they have any Biology or engineering majors on their team. Guess we will not rule out d3 if we get an interested coach. We’ll see how much $ they can offer.
