Best colleges and universities that give merit scholarships for outstanding high school students

To clarify, son knows he can apply to an Ivy and if he gets in and wants it, we will make it happen. He also knows that he wants to go to medical school and feels he should save his 529 money to help with that. He is torn between prestige and price. We are also. Plus we encouraged our oldest to go where the scholarships were so we want to be fair. Junior son has worked so hard though and we are hesitant to hold him back from the prestigious schools. However, husband and I are also aware of the benefits of the big fish in a small pond theory. Thank you all for your input.
