It's not difficult. They are all zero based teaching. The college has a special specialty for junior high school graduates, which focuses on learning computer application skills and emphasizes practical operation ability. Junior high school graduates can learn it well; Specialized computer colleges can teach students in accordance with their aptitude, so that junior high school graduates can not only learn computers, but also learn and excel, and succeed in employment.
I'm a sophomore now. It's not too late. In fact, apart from talent, any major is difficult to learn. Don't underestimate the word "specialized". Many people said that they didn't learn anything after graduating from college. On the one hand, because of enrollment expansion and other factors, the current level of universal college education has really declined compared to the previous years. For example, I heard from my brother who majored in medicine that their teacher said that their exams were many times easier than they were in those days (in fact, students already felt very difficult.) On the other hand, we really didn't want to make progress. Students who are really willing to study their own majors can't stop them from seeking knowledge. Don't say that you can't understand C, C++, have you previewed, done background investigation, reviewed mathematical knowledge, and practiced after class? In college, there should be more time for you to do the preparation and rehabilitation work. Don't be lazy. Be professional. I am an English major. Many of my classmates who used to have poor English can almost be said to have zero foundation. Even though they did not understand many things, they still learned English through their own efforts. Take action.
