<p>Jeff,
I think you have a decent chance, but strongly recommend that you take the most challenging schedule that you can your senior year. Taking only 3 AP classes throughout your high school career is a little bit light. Also, definitely interview. Even if you live a significant distance from Brandeis you can request an interview with an admission rep if one is planning on going to your area, or they can find an alumn to interview you. Finally, get your teachers and parents to review your essays before submission. My daughter did that and I think it helped quite a bit.</p>
