2. Sichuan University of Science and Technology belongs to two majors. If it is a junior college, the tuition fee will be charged according to the unified two majors. However, after you are promoted to the undergraduate course, the school only recognizes that you have 45 credits for the undergraduate course, so you have to make up a lot of credits in the future. One credit is 45 yuan, and each major seems to be different. If you are an art student, it is 150 credits.
Personally, it is better to read three books than to read a junior college. In addition to high tuition fees, the three books are all independent colleges set up by some universities to find money, so they become the so-called three books. Don't say three, just pick one. Except for famous universities, there is no difference between your junior college and your undergraduate college. No matter what you study now, your salary will not be much better after graduation, which needs to be supplemented by textual research or something.
4. There is no best major. You can choose your major according to your own preferences and actual situation. It is ok to find a job in every major, especially in management, such as accounting. Then there is material chemistry, the best major of Sichuan University of Science and Technology, and then bioengineering and machinery can also be used.
