Is it fair to all applicants if you were admitted to a prestigious law school partly because the dean endorsed you? Would you pursue your studies in this school?

Consider this:
Let's say you came from a good law school and have good grades. But for some reason, you decided to transfer to an even better school. To be admitted, you need high grades and entrance exam scores . Fortunately, your only problem is how to ace the entrance exam.

Since this school has a very low acceptance rate, you asked the dean (who is somehow connected to you) to consider your application should you pass the entrance exam. If you were admitted to that school, is it advisable to study there even when you were just endorsed by the dean? Is this fair to other students? Would you take the opportunity?

BTW: I'm not from the U.S. In my country, every law school prepares and administers its own aptitude exam.
