To Marc: I'd like to thank you for being such a great teacher (and the king of peptalks). When I came to IES, my math score was a 640. By midterms it was 670, which was very disappointing. Still, you believed in me and knew I could do better. Then I got a 780 on the final and I died (figuratively, of course). It was such an awesome feeling. You said in your comment about my final that you were really proud and thought I could do even better. Guess what? I did. I got a 790. So much of that score can be attributed to you, so thank you so much for everything.
