The content of postgraduate study will be more systematic, and the free time will not be as much as that of undergraduate study.

Graduate students mainly learn some basic knowledge, experimental skills, literature reading and retrieval, have a preliminary to moderate understanding of their own research fields, and have the ability to talk about the mechanism behind literature retrieval and prepare opening reports. After preliminary exploration and pre-experiment, after completing the opening report, it is time to start the formal experiment. We should concentrate on the experiment and correct our mentality. We should also study the writing of SCI (various lectures and online resources) while trying to improve the experiment.
