It's best to start preparing graduation thesis (design) as soon as possible. It's not easy, but once every four years is the key.

Graduation design is a project completed by students independently, which is finally presented in the form of degree thesis. According to the current rules and regulations, the graduation design of most schools is compulsory, that is, you have to pass the graduation design exam to graduate smoothly. Generally speaking, the graduation project is started at the end of senior year and then completed in the next semester of senior year. Finally, the completed results are presented in the form of papers, and further evaluation is made by teachers in the form of defense.
