My sophomore year of high school I did not have a proper calculator. I used a tiny (handsized) pink calculator that had come with some bubble gum I got while Trick or Treating some years back. How ridiculous to reach Geometry and not have a good calculator, and I was teased by my teacher but it was a class of two, so it didn't matter much. The other boy in my class often showed up to school in a Spanish wrestling mask, so I really didn't have anything on him.
I upgraded to a bit more stylish gray calculator that had more functions, but I eventually got my TI-85 over the Christmas break of my Junior year while I was in Algebra II. I really did put it down to the last minute. I barely knew what I was doing.
Since I got a 500+ on my SAT & I took four years of math in high school, I got to avoid math in college. Almost every single Emerson College kid I know has avoided math -- way to go! So we end up stupid with no future of doing well on the GRE -- at least, I wouldn't have done well. Although, I just don't do well on tests.

The one thing that I regret is not keeping up with Japanese while in college. I studied for four years and now five years have passed since I've studied it. I hear it everday (while I'm here in TX) between my grandmother and mom, but it's not the same as speaking it myself. It's true that I pick up words and I still remember how to write hiragana and can recognize most katakana and even a bit of kanji, but it's all fading and fast.
It's the one thing I didn't want to lose.
