But my psychology course was completed in one year. It's hard to say whether it's hard or not. It varies from person to person, but what matters is your persistence. It must be true skills to pass, there is no possibility of muddle through, only study hard to pass, and you can never pass without studying hard.
After completing all the courses in the college with strength, the professional level will never be worse than that of ordinary college students (provided that you have really studied hard). On the contrary, the content inside contains all the contents of the undergraduate course, which will never shrink, but the writing of the textbook content is somewhat different.
It is not difficult for people with perseverance. It is difficult for people without perseverance. The most important thing is persistence. I can finish more than 30 textbooks, which is not what most people insist on, so it is a test of people's tolerance for loneliness.
