The 30th GEL-SIT plenary seminar was held. This time, eight B4 students presented the progress of their graduation thesis research. With the end of the year approaching, there are only two more opportunities for B4 students to report on their progress, including this one. At this milestone, I hope that they will continue to work on the final stages of their thesis research, while maintaining their confidence in their accomplishments so far and maintaining a “having fun” attitude.
