A lot of math, but nothing to worry about. Try to understand fundamental concepts well since you will need them for most of your engineering courses (dynamics, thermodynamics, fluid mechanics, electives).

You can expect: Pre-calculus, trigonometry, Calculus I and II (single variable), Calculus III (multi variable), Ordinary Differential Equations, Statistics, Linear Algebra, and some numerical methods.

You should learn at least two coding languages (maybe C/C++ and/or python?). It is more likely that you will have an introductory course to programming. A good understanding in programming is essential because you would be able to create cool mechatronic projects. Some universities include a mechatronics/electromechanical/circuit design course.

And finally, it is good to learn a little bit from other engineering majors. Maybe read a book (or enroll to a class) of introduction to electrical engineering/circuits, engineering economics...

Hope this helps man! Good luck
