Ha, I was just about to start a thread about spring transfer to Cornell, and then I found this one after searching.
I'm inspired by your determination, Violaghost.
I'm going to apply to transfer to Cornell CAS in spring 2010. I'm also applying to Rice and Washington University in St. Louis, but Cornell and Rice are my top choices (with Cornell a bit above Rice, but not much). I've finished just now my first year of college. So if I'm accepted to Cornell I'll have completed three semesters upon matriculation. Here are my stats:
College:
GPA: 3.98 (A+s in everything except one A- in a class ironically called "learning strategies")
Major: initially computer science, but I've switched to math (although technically I still have the CS major as well)
Course load: After next semester, I'll have done five honors courses, five 4000 level math courses, calculus-based physics, and four computer science classes.
Recs: I haven't gotten these yet (I'll be getting one very soon in fact), but just last semester two of my professors had the Honors College here send me letters congratulating me on my success in their courses, so I should be able to get good recs
ECs: I'm a programmer in and primary contact for the Game Design Club here; we're just an independent development team that develops games in our spare time. I'm a member of the math club and have been pushing to get my school to participate in the Putnam exam, but nothing's come through yet.
Work: I work at a software development company and develop semantic networks for an online automated essay grading service. Some of the assignments I've developed are used at universities throughout the nation (that part's pretty intimidating).
High school:
GPA: It was something like 3.98 as well. I have no idea why both my GPAs are exactly the same. Haha.
ACT: 34E, 34M, 30R, 30S, 11 Writing (32 composite)
Course load: I took the hardest courses offered, but I have no APs because my school didn't offer any!
ECs: I participated in Science Olympiad all four years, and got way too many medals to list here. I also got 1st place in a programming competition at a nearby state university all four years of high school. I also did community service. We set up recycling bins around the school and at football games and maintained them, and every weekend we cleaned up trash off the side of a road (different road each time). I also spent a really significant amount of my spare time teaching myself to program. My school offered no programming classes at all. I taught myself when I was 11 or 12 without any teachers or mentors or guides or peers. I'm pretty proud of those 1st place finishes because of this.

Work: I didn't work at a paid job but I did some other community service stuff in the summers, like packing clothes to be sent to the Ukraine for people in need.
Essays: I haven't written these just yet, but I'm brainstorming them.
I have extremely specific educational goals I want to accomplish as an undergraduate. My overall goal is to become a research mathematician. I have a list of topics I want to study as an undergraduate before going to graduate school, and I want to transfer to Cornell because their math program is strong enough to let me accomplish this. They have a strong curriculum in algebra, topology, and algebraic topology. I also want to study differential geometry (and calculus on manifolds). I studied this in my spare time in high school, and I'm very disappointed that there are no undergraduate courses in this at my current school. However, Cornell has strong undergraduate and graduate offerings in this subject. I also thoroughly enjoy proofs and proof-based reasoning, and Cornell's courses are significantly more proof-based than those at my current school. I feel this is very important since I want to go to graduate school, and I hope the admissions committee will understand.

I also want to participate in the Putnam exam, and Cornell participates (and does very well) whereas my current school doesn't.
I want to communicate all this in my essays so they know exactly why I want to go to Cornell, what I want to do there, and why I believe it will help me meet my goals.
I hope to hear updates on everybody's progress through the grueling admissions process! Good luck to everyone!
