Your engineering curriculum includes a calculus sequence. A placement exam determines your first class in the sequence. Mechanical Engineering, Electrical Engineering, Civil Engineering, and Environmental Engineering require up to MTH 117. Biomedical Engineering and Computer Engineering require up to MTH 115. All majors require a class in Differential Equations. You can see a description of calculus classes here.
High school calculus is not a requirement for entry into our engineering programs. However, strong performance in high school pre-calculus classes is definitely helpful.
The first year is designed to be pretty common across the engineering majors. It allows you flexibility to explore the majors while giving you the core Mathematics and Science courses that you need for your Sophomore engineering courses.
There is no requirement to have a laptop. All engineering programs have software and hardware available for students in the engineering computer labs and resource rooms. However, many students have laptops as this allows them to work on assignments at different locations and at different times.
You have to declare an Engineering major when registering for sophomore year courses. This happens around the 6th week of Spring term (mid-May) of your first year. You may have come in as an Undecided Engineering major or made an initial major selection but you may change your designation at any time during your first year (and can change multiple times).
All engineering programs have the Fall term of the Junior year as the default option for term abroad. However, many terms abroad run in other terms and it is possible for engineers to go on these terms abroad with some planning. The best thing to do is to let your adviser know your preferences for study abroad early so they can work with you in scheduling your courses to best accommodate your study abroad plans.
