I feel that listening carefully in class is not enough for this major, and I have to spend a lot of time on self-study after class. It's better to study this major with goals, such as software development or embedded development or network. All three computer majors have computers, so they are crazy and Warcraft takes off. It's hard to avoid temptation, and it's hard to teach yourself in the dormitory. Again, if you have a goal, you should study for at least one year before you go.
