I am also a student of Northeast Agricultural University. VF and VB are the courses with the highest failure rate every year. There are many failures in written test and computer operation. The written test mainly includes three ways: multiple-choice questions, fill-in-the-blank questions, true-false questions, procedural questions and procedural questions. Although it is said that it comes from exercise books, there are not many similar problems in fact. Let's study hard. Come on!
