In some universities, PI will also encourage students to write summaries, so that students can have a more comprehensive and cutting-edge understanding of their research fields, and on the other hand, they can broaden their research ideas.
If the undergraduate wants to write a summary to add points to the research, it is recommended to know the research policy of the college first and see if the literature summary can be included in the paper, which is generally acceptable unless the college has higher requirements and must be a research paper. I hope it helps you!
