If you're applying for fall 2015 transfer admission, remember that we require final high school transcripts. If you're home for the holidays, you could get a jumpstart on gathering materials and either pick up a sealed transcript from your high school, or simply take a break from the netflix queue, your video games, or that leisure reading you've been meaning to get to all semester, and order your transcript by phone or online. You may send these transcripts now, ahead of your application, or if you feel more comfortable waiting, that's fine as well. Just do it by March 1 :)
For students who attended high school abroad, start working on getting those transcripts now, or maybe while you're home for the break. In our experience, it can take weeks to get these kinds of transcripts, so our advice is to start early.
