<p>To get a A.B./Sc.B. you have to stay for a fifth year. It is an option open to any Brown student, and you are allowed to change your mind about pursuing it at any point. In other words, your admission will be considered in the same pool as everyone else, A.B., Sc. B., or undecided.
By the way, you can double or triple concentrate in anything you want and finish in four years. The fifth year is to get two separate degrees.</p>
<p>Ah, that number had me scared. I was worried that through human error I had applied to a Huntsmenesque program and was making admission that little bit harder.</p>
