Most colleges have a pretty well defined course requirements for a degree in Mechanical Engineering. At my school, you did not declare which engineering program we were taking after freshman year, the ME programs requirements were slightly different than the other engineering requirements. The counselors at your college or University can help. Typically freshman year include calculus, Physics, Chemistry, English,
When it comes to electives over your 4 years, I recommend technical writing if not already required. Take the harder technical electives that highlight areas of interest. Project classes are impressive to hiring managers.
