Due to the changing COVID situation in the past 2 years, the
students of X Academy have experienced four different curriculum
models in the past four semesters. In the first semester, before
the pandemic began, face-to-face courses were held as scheduled. In
the second semester, when the pandemic reached its peak, the
courses had to be conducted entirely online. In the third semester,
as the pandemic subsided, online and face-to-face courses were
conducted in a mixed mode. Finally, in the fourth semester, an
outbreak on the campus caused the entire school to suspend classes,
and only recorded lecture videos were available. The table below
shows the semester GPAs of five students that were chosen at
random.
