Many people say that the knowledge of high school is forgotten in college, so will the knowledge learned in college be forgotten after graduation? I want to work in this major, if I forget.
What I learned before will definitely be forgotten. That's not the point.
The key is that knowledge is updated faster and faster now, maybe once every three or five years. Maybe the old things can't be used.
If you want to engage in this major, you must always learn new frontier knowledge.
