I second Univ of Scarnton. They have a good pre-med and pre-health programs. Also look at Juniata College. You will likely get merit aid at both. I would also emphasize that it’s important to have some financial safeties as well - such as Slippery Rock or Millersville . Regional public universities usually have pretty good biology departments since bio PhD’s are so abundant. You may have to be a bit more open on the size of college, as the somewhat larger colleges are going to have more support for the types of programs you’re looking at, and also you may need to be more flexible because you are looking for merit aid.
Suggest that you sign up for AP Stats if possible. It will give you an AP math course, and statistics is useful for pre-med. I think you’re a very good candidate overall and think you have realistic expectations. I agree that the lack of transparency for merit aid is frustrating. In a reasonable world, $30K per year should be fine for a decent college education, but that’s not our reality, unfortunately.
Edited to add: I don’t think it’s necessary to focus on neuroscience major per se. A lot of colleges have rebranded their biology degree as “neuroscience” with some minor modifications. You should focus on the department resources, faculty and support for pre-med and pre-health programs.
