My Interests and Strengths
Math
I am immersed in competitive math regarding various competitions such as the AMC 10, COMC, CLMC, CJMC, Gauss, Mathematica and BCC. Currently, I am working towards learning more advanced high school competitive math to excel in competitions like the AMCs. Inspired by my sister Grace, my goal is to triumph at an international level.
Programming
My experience in programming spans both competitive programming and project development. While I study competitive programming techniques and solve problems on DMOJ (check out my resources hub!) to prepare for competitions such as the CCC, I work on projects such as this one (check out my portfolio for other projects) to expand my skills in multiple langauges and interfaces.
Science
My experiences in the LTSC, or Let's Talk Science Challenge, fueled by a yearning to understand the world, have led to my interests in Physics, Biology, and Chemistry. I hope to expand my knowledge of various scientific concepts with the goal of participating in more competitions in the future.
