Help me select University of Michigan, NYU or Schreyer Honors College at Penn State?

<p>As a senior in H.S., I have narrowed down my choices to these three schools. Cost is about the same. I love the location of all and campus is not a factor. My plan is to major in Biology on my way to pursuing a career as an Orthodontist. I want to choose a college that will:
1) Best prepare me for dental school
2) Give me the best chance of being accepted to dental school
Can you please give me advice, I am truly torn. Any other inform that will help me select would be great. Thanks everyone.</p>
