Cooper Anderson
Chemistry teacher | Tutor for 9 years
I hold a degree in Chemistry from Youngstown State University, specializing in analytical chemistry and chemical kinetics. With a passion for unlocking the mysteries of the chemical world, I bring years of experience in tutoring and teaching. My approach emphasizes clarity, problem-solving, and fostering a deep understanding of the subject matter. Whether it's balancing equations or delving into complex reaction mechanisms, I'm dedicated to guiding students toward mastery in chemistry. Let's embark on this scientific journey together, where curiosity meets knowledge, and every question leads to discovery.
