Category I --- The mode of delivery of content examined in these questions was identical in 2019 and 2020 (e.g., via assigned reading material or self-study exercise). These served as our Control Questions
Category II --- There was a difference of 3% or less in % Correct between 2019 and 2020
Category III --- There was a difference of 4% or more in % Correct, with 2020 Zoom delivery showing a better performance or higher % Correct than 2019 on-campus delivery (2019 < 2020)
Category IV --- There was a difference of 4% or more in % Correct, with 2019 on-campus delivery showing a better performance or higher % Correct than 2020 Zoom delivery (2019 > 2020)
Other --- Questions for which performance in the 2 years cannot be easily compared, either because of a change in the wording of a particular question or because the mode of content delivery was altered (e.g., a self-study exercise in 2019 was replaced by a lecture in 2020)
^aIn Categories I – IV, identical questions were used to assess the same content
