There are several reasons for the delay.

First, the reasons for academic performance-the failure of the course led to the delay in graduation, and the credits that should be completed were not completed. In fact, this reason is the last thing that should happen, because it will not only affect graduation time and waste working time, but also probably affect job hunting. Because you haven't completed the corresponding credits, you have to retake them. Reconstruction not only costs money, but also takes time, which also affects job hunting.

Second, some people can't graduate on time because their graduation thesis is not well written, and they can only postpone graduation. Some people postpone graduation because they are not prepared for the graduation defense meeting, and they have not persuaded their teachers for their own reasons. Some people missed the defense meeting for their own reasons (such as incomplete graduation materials and incomplete personal information files) and asked for an extension.
