Hiyas KJCUNC! Somewhere in my travels I saw 2009 transfer stats, but I can't seem to find them now.

The GPAs and scores were higher though.
Some advice for everyone that I've learned from admissions and other transfer students:
Those of you reapplying: For the love of god don't submit the exact same thing you did last year. Show them you've grown and explored. ESPECIALLY not essays. Resubmitting the same essays basically works STRONGLY against you, and essays are weighted just as equally as academics for transfers.
Don't take classes to pad your GPA. UNC would rather see you get a crappy grade in trying something new and/or difficult than you taking "easy" classes. I transferred in with 3 Cs.
Don't stress yourself over your freaking GPA/test scores. Being here means you WILL see those applicants with the 3.7+ and you'll feel like you don't stand a chance. I went through that stress last year when I applied with my 3.46. I got in. (I'm writing this from on campus in between classes, actually!) Getting down on yourself won't help you, and especially if you go back and review the stats of people who got in with their 4.0s and ECs of curing cancer, saving the world, etc., you can start feeling like you're inadequate. This can translate to desperation in your essay if you write it after comparing yourself to others.
Don't kiss ass in your essay. Carolina knows how good it is, they don't need you to tell them. I heard that from an admissions officer I spoke to. What they DO want to see is some of who you are, and what you demand from Carolina. How is Carolina the next stop on your journey, is it a specific program they offer? Something locally you hope to get involved in while at UNC? There are plenty of good schools, why specifically Carolina and how does it fit in with your goals and who you are.
They want to see that you try new things, not just academically. This is probably more important than most think. If you're a chem major and all you do are chem clubs and such, that's not really saying much about you, you know?
Carolina prefers junior transfers over sophomores. This is just fact and is stated on their website.
Something I read a lot when I was applying that was just plain untrue, Carolina DOES NOT factor in residency for transfers. Doesn't matter. Anyone else who tells you otherwise (and you'll hear it at least once) is full of ****.
You have to take at least half of the classes required for your major at Carolina. I mention this in regards to choosing classes for spring, anything you take within your major that goes over that amount winds up as general elective credit (I found this out the hard way), which is one less interesting class you could take at Carolina. Use the Undergrad bulletin (here:
http://www.unc.edu/ugradbulletin/intro.html) and advising worksheets (for arts and sciences here:
Academic Worksheets — UNC Advising) to help guide you.
That's about all I can think of for now. Some of it stuff I wish I knew when I applied, lol.
