<p>When you accept, you normally sign on the card that you are only accepting one college. To accept two colleges is "dishonest" and the academic world really hates that. A lot of colleges have honor codes and you are expelled for cheating on exams. When you signed both cards, it said that doing so could result in your acceptance being revoked.</p>
<p>And colleges do share information to some extent. Not every college in the country is connected to every other college, but colleges in the same area or the colleges that cater to the same group of applicants often share information.

Any decision is better than no decision.</p>
