<p>The important thing is to note that deferral is not rejection; it is just not a clear EA acceptance. If it is the students first choice, you can send a letter affirming that and you can also keep the school informed of any later accomplishments that are relevant. I'd advise a considered letter, not just a knee jerk one, and hopefully there is a Senior year sucess to include. Try to think why you are borderline and address it.</p>
