Research guarantee refers to those who are directly sent to graduate school by the school without going through some preliminary procedures such as written examination, and determine the students' academic performance and comprehensive quality through an evaluation form, which is within the allowable range. Simply put, students are excellent enough at the undergraduate stage, and the school recognizes that they are qualified and can go to graduate school without passing the postgraduate exam. Achievement insurance is a relatively centralized way to ensure research. In the junior year, students who have the opportunity to study and those who are wandering on the edge of the study need to be highly valued, because in this year, everyone's enthusiasm will often rise from quantitative change to qualitative change. If you want to make a turnaround, you must make good use of it in your junior year. Students who want to be sent to foreign schools through academic research should pay attention to their academic performance and improve their academic level. If they can make several articles published in core journals under the guidance of their teachers in their junior year, the chances of being sent to foreign schools will be very high.
