Baidu has * * * information. Others need to be retrieved from the library. What kind of test paper library do you want? Usually this teacher will give it to you. Of course, some teachers are partial and don't give it. You can go to csust's homepage or online teaching platform. The second and third floors can be connected to a pure intranet, where you can find the question bank of the intranet. Maybe what you want is in it. I have to see for myself. It's not clear here. Anyway, these are the right directions. Find it yourself. Information retrieval is also a kind of ability, you should learn it in university!
