Hello, I'm a design teacher. Many students will ask you this question. Actually, I also want to ask you, if you didn't learn anything in college, what's the point of spending so much tuition and four years? Just for a diploma? It can be said that a diploma is not as valuable as three years of work experience. School learning is very passive and there is no big framework to grasp. Of course, the learning process divorced from practice is prone to problems, and some teachers are not responsible. My advice to you is not to take any training courses, but to find a design company that recruits students in your city. Even if you work in it for half a month, your question will have an accurate answer. My answer is: learn the software well in four months and go to the company for internship. I wish you early success.
