Dear all, according to the university epidemic control regulation, we will have this course online using the VooV meeting platform. All students are required to download and install the software asap and test it to make sure both the microphone and camera are working properly. We all gather all students to test the platform 2-3 days before the class. The attached documents are the course syllabus, grouping info, two guidances, and one sample slide for system testing. Please read the course syllabus very careful to make sure you are clear about requirements in the course. During the system testing, all students are required to open the slide and share their screens for testing.
