How does this schedule look in terms of difficulty for the first semester?

I’m a Pre-CSE major.

ENGR 1181.01 (Fundamentals of Engineering I)
PHYSICS 1250 (Mechanics, Thermodynamics, and Waves)
MATH 1161.01 (Accelerated Calculus I)
CSE 1223 (Intro to Java)
ENGR 1100.06 (CSE Survey)

Isn’t a cakewalk, but shouldn’t crush you so long as you adapt to college well.

1181 isn’t hard at all, although it can be pretty time consuming with all the lab reports, especially if your team isn’t that great.

Physics is typically a bit rough. Take it seriously, it gets really hard really fast once you get to the stuff that isn’t typically covered in high school.

CSE 1223 is pretty easy, and is a total joke if you have even the most basic knowledge of coding.

Survey basically isn’t a class.

Math 1161, however, is known to be pretty hard for no particularly good reason. There have been a couple of “red dit” threads in the last few weeks about that class, and the overall consensus is that it’s not worth taking. Maybe look at those threads (PM me if you want me to send them to you) and consider switching to 1151 (which isn’t exactly a walk in the park itself btw).
