Today I returned to face-to-face lectures. This Monday is the start of the second week of my seventh semester. I am a math student at Universitas Sumatera Utara (University of North Sumatra). Since 2020, I've been studying online, only in the last semester I've had one face-to-face but hybrid class (some online, some face-to-face (I was face-to-face)). Today I entered three classes. Statistika Matematika II (Mathematical Statistics II) with lecturer Dr. Sutarman, Pengantar Simulasi (Introduction to Simulation) with lecturer Dr. Esther S. M. Nababan, Metode Penelitian dan Penulisan Karya Ilmiah (Methods of Research and Scientific Writing) with lecturer M. Romi Syahputra, M.Sc.
