The biggest mistake I made in college was not listening to my advisor and thinking that "recommended" courses means I could get by with taking something out of order. For example, taking Circuits I without taking Electromagnetics (and likely Diff Eq) first is a bad idea even if it's technically allowed. Another mistake is to not understand that some of the harder classes need to be spaced out or you get burned out. There seems to be a big ramp up from first year to second year coursework. 75% or more of what you learn is going to be obsolete or not needed in your career. The problem is you don't ever know which is the 25% you'll use. That may even change over time. And those English/Comms classes are helpful while still being less of a PITA than your other coursework so they prevent some burnout. The most fun classes I had were a Foreign language which was taught by an actual native speaker, and a Comms class which just had a nice mix of students.
