I was deferred SCEA from Princeton, and plan on sending a letter of continued interest to the school. I'm not confident it will play a substantial role in my admissions decision, but I would rather be rejected knowing I tried everything than suffer the same result without having explored all avenues. Within the next three to four weeks, however, there will be a drastic increase in tangible results from a nonprofit I direct, and I would love to include these data in my letter. To do so, however, I would need to submit it at the end of February. Is this too late to send in the letter? Also, if I do end up sending in the letter, is it better to do so through snail mail or through the Princeton application portal? Thanks in advance for your responses!
