You should prepare for a career as a chemical engineer in high school by completing science and math classes, particularly calculus. After that, you'll need a bachelor's degree in chemical engineering , especially from a university that offers concentrations in your chosen sector. A master's degree may be necessary if you want to work in management. Step 1: Study Chemistry, Physics, and Math in High School. Chemical engineering candidates must compete against a large number of other applications. As a high school student, you should begin your preparation early by enrolling in chemistry, biology, physics, and math subjects. Taking college preparation or AP classes in these subjects can also help you get into college, and particular studies in trigonometry, algebra, and calculus can help you satisfy college admissions criteria. Extracurricular activities in science, technology, engineering, and math might also be beneficial. Engineering summer camps and research oppor...
