This is a very pragmatic question, and I would like to share my personal views based on my own experience of taking the retest.
First of all, for students with rich experience in scientific research, projects and professional competitions, try to focus on the practical experience with higher participation, which can also give teachers a guiding direction for communication, so that teachers can discover their scientific research potential, and even have the opportunity to reach a consensus with their supervisors, which will have a more positive impact on the re-examination and will be more efficient.
If you have rich scientific research experience, some projects that are not highly involved can also be written in the resume, even if there are some content you forget, you can also fill in with other practical experience, and the teacher will not think that students are making up practical experience, after all, there are other practical experiences that can be corroborated, and some practical content will inevitably be forgotten if you are not exposed to it for a long time, which is also normal.
If you have very little practical experience, or even no decent practical experience, as long as you have participated in the practice, you should still write, after all, having practical experience and not having practical experience are different, even if there is no result in practical experience, it is not a shortage, if the participation is relatively high, you can still prove that you have a certain potential for scientific research.
For the practical projects that you have participated in, but due to time and participation, you may not be familiar with it, it is recommended to surprise before the retest, at least to be able to present what you have done, even if it is to do data collection and collation related content, it is also valuable.
Taking me as an example, as long as the students have practical experience, I usually focus on this experience with the students, after all, this is a more efficient way to understand the students, and it will also relax the nervousness of many students, so as to present their abilities more completely.
Generally speaking, as long as it is a scientific research activity participated in during the undergraduate period, whether it is a project project, a professional competition, or an achievement sharing and other activities, it should be presented.
Finally, if you have any questions related to computer science, please feel free to communicate with me.
