I will post what you already know. Math, physics, and computer science are good for engineering majors. You will likely need to write code by the time you get into junior/senior college years of engineering. I wouldn’t worry about it all that much. You can take calculus and computer science classes freshman year. There are students who decide on an engineering major whose high schools do not offer calculus or CS.
In answer to your question…yes that is a good course load. Keep in mind for schools like Stanford you not only need those classes on your transcript but you need to get A’s too. Good luck!
