Well ~ ~ ~ junior (or junior), hehe, you have worked hard. You must know so much as a freshman. Let me tell you something. Sophomore, you can transfer through relationships. The cost is1~ 20,000. Since you don't want to spend money, forget it.

Second, in the second semester of sophomore year, that is, in April and May, there will be oil companies to sign some orientation students. As long as you pass CET-4 and have excellent academic performance, you will have the opportunity to transfer to these good majors, such as masonry, storage and transportation, but these companies usually sign for 4-5 years and work hard. Since you are in charge, it doesn't matter whether you are a man or a woman.
