COVID-19 pandemic impact on student achievements

The COVID-19 pandemic created a natural experiment for comparisons in performance during in-person versus synchronous online and hybrid learning mode. We tracked changes in student achievements across the first two years of their engineering studies. The inquiry was conducted on 787 students.
