I'm not sure what I want to study or do in college. What top universities are most flexible?

<p>Wow, these are very helpful! Thank you for the replies.
Another question, I’ve heard LACs are often flexible due to their small sizes, and they are an attractive option, but I’ve heard they often lack research opportunities presented by national universities like Stanford or Harvard. Is this true, and to what extent? </p>

<p>Also slightly off topic, but what would you say my chances are at schools like Princeton, Harvard, and Brown? Obviously there’s really no point in contemplating college pros/cons if I can’t get into them.</p>
