Every university has different time for writing papers and defending, so let's explain it to you in the form of interval time (this answer only summarizes the time of most schools):

First, determine the direction of topic selection. Most universities generally start in11-65438+February. Secondly, writing papers generally begins in February 65438 and ends in the following year 10;

Note: In the process of writing a thesis, undergraduate graduates will modify the content of the thesis once or twice, and it is not excluded that students who are not good at writing will rewrite or modify the content of the thesis three or four times.

After the content of the paper is determined, it is generally checked in February-April (some schools reply first and then check); After the duplicate check is passed, prepare the defense, and generally defend the thesis in March-June.
