All engineers need a knowledge of mathematics and physics, no matter what their special field of work is. Most young people who wish to be engineers begin studying these subjects early in high school. (1) An interest in mathematics and physics is essential because every engineer must work with these sciences. Students preparing for engineering college should also study chemistry, mechanical drawing and other science subjects that are offered. (2) A good command of language is important because engineers must be able to talk and write clearly. A knowledge of economics, history and other social science subjects also is helpful. To best fulfill their duties in society, engineers need to know not only how to do their work but also how their work will influence other people. They need to be able to make decisions on many problems. Engineering colleges usually take four years to complete, although some schools give five-year courses. (3) When they are sophomore, an engineering student begins to concentrate in special field. Part of the student’s time is spent in the classroom, and part is spent in the laboratory doing experiments. In some schools, students spend part of the year studying and part of the year working in their chosen field. This gives them the opportunity to apply their knowledge in practical situations.
