I am a sophomore mechanical engineering student at the University of Iowa. In high school I took classes like physics and higher level math (calculus 1, college statistics, college algebra). I tutored kids who were struggling in classes I had already taken in high school. I am proficient in most engineering math including statics, calculus 2, physics, matrix algebra, and other classes related to engineering as well; including chemistry, C++, and MATLAB coding. I am very good at public speaking. I did theater in high school geared towards younger people and I have experience with younger people through volunteer experiences in my hometown as well.
