The topic selection of graduation thesis should have scientific or practical value, great realistic possibility and moderate size. The topic is too big to grasp the angle of the problem. In addition, the topic is too big to analyze the problem in depth and in detail, and it is easy to generalize.

The topic is too difficult.

Due to the limitation of time, energy and materials, students should pay attention to the difficulty of selecting topics, and they should not go beyond their own professional fields. Although the topic of graduation thesis can't be too big and difficult, it can't be too small and too simple, otherwise the workload of graduation thesis is not enough and the quality will not be very high.

This topic is out of date.

Don't be too old-fashioned If there are too many similar articles in the literature, it is better to change the topic. Don't copy other people's materials and conclusions. On the basis of predecessors, we should dare to ask questions that have not been raised or have not been completely solved. It is best to choose more topics closely related to real life, contemporary economy and scientific and technological development, and pay attention to studying new problems in real life.
