Well, I cannot say you will not be stressed out in college, but it is all how you approach your scheduling of your coursework. There is a lot of focus that comes into your major, Civil Engineering. You have to take math courses, computer courses and so on, so I suggest you do not take all these classes at once. Maybe take two classes a semester or three as a part-time student, so you will not be overwhelmed and you can learn more calmly and understand each class and enjoy each class. If you are living on campus you may have to be full time, if so only take 12 hours that is 4 courses that are 3 credits each. Depending on your University policies for on campus students. But I must say again, do not overload your schedule, and you should not be stressed out.
