You only need to learn one course you like in a technical school. Do you need to learn the rest: Chinese, mathematics, English, etc?
Of course, otherwise I won't graduate. Professional knowledge is the most important, because it is the cost of eating in the future, but the language is not good, so it is inconvenient to work in the future. Mathematics is often used in work, especially in mechanical and electrical majors. Without common sense in mathematics, it is difficult to adapt to work. English is a compulsory subject for future promotion, so you have to learn it.
